As has been mentioned, you can't daisy-chain multiple Thunderbolt displays to an Air. Two possible add-ons that'll allow you to connect an additional external display:
Matrox DualHead2Go (in action hooked up to an 11" Air)
DisplayLink adapter
I've used the latter and they work pretty well for non-intensive applications.

Your Air supports the internal display as well as only one ThunderBolt external display. As commented below, the Mid 2012 Air can run two ThunderBolt displays. Physically you can daisy chain as many Thunderbolt Displays as you have money, but the first limitation you will run into is the graphics card.
The official Apple knowledge base article lists the ...

The Apple press release says "supports DisplayPort for high resolution displays and works with existing adapters for HDMI, DVI and VGA displays", but this is referring to the Thunderbolt output port (for daisy-chaining). The Thunderbolt Display will not work with a non-Thunderbolt machine without an adapter.
But unfortunately now that the they have started ...

According to this source, this should work. This other source confirms it. These are the troubleshooting steps I would try:
Run all software updates on both the iMac and MacBook Air. A lot of times there are firmware updates that address issues like this.
Open System Preferences > Displays and click Detect Displays.
Reset the PRAM on both the iMac and the ...

Yes - you might be overlooking that all the Display Port adapters work perfectly well with Thunderbolt macs.
Just place it at the end of the chain. It's not an issue since your VGA or HDMI device isn't going to have another Thunderbolt port in the chain to send the data further. You are necessarily connecting at the end of the line.

Another option to to use a display multiplexer, like the Matrox DualHead2Go DP. This will have much better performance (frame rate / snappiness) than the USB solution, at about 4X the price. It's best with matched dual external displays - or triple; there's also a 3-monitor solution. I haven't used one personally, but have recommended it to clients with ...

I am not aware of any manual that contains this information but here is a breakdown, since this is one of the big reasons I got a MacBook originally.
The mini display port allows you to add an additional monitor to your MacBook. Support for this is built into the OS directly so you simply connect your external monitor using the correct MD/VGA or MD/HDMI or ...

First generation MacBook Airs could only drive a single display. And the current generation, Thunderbolt-equipped, MacBook Airs do not support more than one external display via the Thunderbolt port. The graphics chip used in these Macs isn't up to the task of driving extremely high resolution display combinations.
Reference:
Unfortunately, this ability ...

No, such an adapter does not exist and is unnecessary. Since Thunderbolt is backwards compatible with Mini Display port. If you look at accessory options for the MacBook Pro, you will see only the following display output adapters available:
Apple Mini DisplayPort to DVI Adapter
Apple Mini DisplayPort to Dual-Link DVI Adapter
Apple Mini ...

No. DVI-D only carries digital signals. Most (if not all) DVI -> VGA converters use the analog signal DVI-I carries. A mini DisplayPort to DVI connector will only pass on digital signals (as you correctly identified by referring to it as a DVI-D signal), so your DVI to VGA adapter is left out in the cold. You need to get a mini DisplayPort to VGA adapter.

Simply plug in one DisplayPort/Thunderbolt display or video adapter per port. That gets you two screens in addition to the iMac screen.
There is a little confusion over multiple displays on one thunderbolt chain and real experience is limited since no thunderbolt monitors are shipping widely as of mid-August 2011.
If you care about the details or ...

Thunderbolt is a superset of Displayport Apple page on Thunderbolt says
And because Thunderbolt is based on
DisplayPort technology, the video
standard for high-resolution displays,
any Mini DisplayPort display plugs
right into the Thunderbolt port. To
connect a DisplayPort, DVI, HDMI, or
VGA display, just use an existing
adapter.

Thunderbolt is different than other connectors in that there are two 10 Gbps signals multiplexed on one physical connector/cable assembly. The DisplayPort signal will go down the chain of devices uninterrupted so the full DP bandwidth will get to the monitor that will ultimately end up at the end of the device chain. Of course new display hardware could be ...

As has been said in the other answer, you are restricted to a single external display with the built-in hardware.
You can however add extra external displays using USB based display adapters. For example I use one of the DisplayLink adapters. Some of the DisplayLink adapters can do 2048x1152. There will be a limit to how many USB adapters make sense, before ...

The spec page for the display implies very strongly that Thunderbolt displays will only work with Thunderbolt Macs.
This happens to concern me since I own a previous-generation iMac (pre-Thunderbolt) and really wanted to have the option to use it with a Thunderbolt display. So I asked the guys at the Apple Store.
The Apple Store told me no, it will not ...

Yes, but it's not worth it.
You would have to take the laptop apart, design and engineer a custom converter to drive the LCD interface (internally, it's going to use LVDS to handle the interface between the laptop's motherboard and the screen), and power it somehow. It also would probably render the macbook from which you removed the screen unusable as a ...

No this will not work. Check the system requirements for the Apple Thunderbolt display.
System Requirements
Thunderbolt-enabled Mac computer, including MacBook Air, MacBook Pro, Mac mini, and iMac
OS X v10.6.8 or later
As of yet there is no way to add a Thunderbolt port to a Mac that did not ship with Thunderbolt.

Here's one example of someone running two 27" displays at 2560x1440 via Thunderbolt/DisplayPort plus an HDMI display at 1920x1200:
http://blog.macsales.com/14241-macbook-pro-15-with-retina-display-can-run-3-external-displays
The Thunderbolt ports officially support up to 2560x1600 so that resolution shouldn't be any problem either:

Plugs are the same, cables are not. The thunderbolt cables contain chips and firmware.
I haven't used the new Thunderbolt display, however I am aware of the following:
MiniDP Macbook -> MiniDP iMac 27: works fine.
Thunderbolt Macbook -> MiniDP iMac 27: works fine.
MiniDP Macbook -> Thunderbolt iMac 27: does not work
Thunberbolt Macbook -> Thunderbolt iMac ...

Yes you can, you can run one monitor from the normal monitor port and another from a USB port but you need a special connector which makes the Air think it has a 2nd monitor attached. Here's an example on YouTube
You need something like the Matrox Dual Head 2 Go which allows you to have multiple monitors with your MacBook. The performance of USB-attached ...

There should be an "Underscan" adjustment in display preferences. Open up the Displays in System Preferences. Have a look at your available resolutions. There should be a 720p, 1080i and 1080p, choose whichever is appropriate for your TV, and a slider labelled Underscan should appear. Adjust as necessary to get the picture right on your TV.

According to this source, you won't be able to do that. You have to have a Thunderbolt Mac and use a Thunderbolt cable to use a Thunderbolt iMac as an external display. This other source has a table that confirms it. Sorry!

According to this source, you will not be able to use a Thunderbolt cable in this fashion.
You can, however, get a Mini DisplayPort to Mini DisplayPort cable from Monoprice for about $5 and that should work just fine.

DisplayLink
DisplayLink makes USB graphics adapters for PCs and Macs. You can add as many displays as you have USB ports and processing power.
You would use the built in graphics card for one of your displays and use the USB graphics adapter for the other side. I would suggest using your three displays in the following order:
Primary: MacBook Pro built ...

Mac OS X should detect the supported resolutions when you connect the display. Your problem might indeed be related to the adapter and cable you are using. According to the HDMI 1.4 spec, standard HDMI cables only support resolutions up to 1080i.
I suggest you use the DisplayPort or DVI port on your monitor instead, and buy the appropriate adapter for one ...

Some thoughts, and things for you to check on:
What model of MacBook Pro do you have? Older ones (pre-Mid 2010) don't have audio out through the Mini DisplayPort.
Have you tried looking at System Preferences » Sound » Output? What devices are displayed, and what have you chosen?
Can you explain what "I have an audio that connects the Mac to the PC in HDMI ...

DVI port cannot output DisplayPort protocols so a simple and cheap adapter (eg the reverse of the one Apple sells as posted in your question) will not work. The reverse does work (a DisplayPort can output DVI signals), hence the proliferation of cheap adaptors to do this.
A number of manufacturers have build adapter boxes to allow the conversion to occur ...

The thunderbolt port and display port are the same port. So it's not two separate ports.
That said, due to the high bandwidth nature of thunderbolt, I suspect we will be able to daisy chain monitors in the future, as well as having thunderbolt "hubs" where multiple devices can be plugged in.
But for now, it's one port. So only one external monitor.

False, Dual DVI means that it has more bandwidth, not that you can attach two monitors. Quote from wikipedia article:
To support display devices requiring higher video bandwidth, there is provision for a dual DVI link. A dual link doubles the number of TMDS pairs, effectively doubling video bandwidth at a given pixel clock frequency.
Dual link ...

Since the mouse pointer gets frozen, you can be pretty confident that the lockup is happening deep down in the system - kernel extensions, hardware interrupt type things.
Assuming you have a great backup and don't mind futzing a bit (and I'll also assume you haven't extra cables, monitors, macs to just eliminate one thing at a time) you can surely try ...
