My devices, including airport stations, keep being assigned a number following their name (i.e. "ATV (3)"). I was hoping Mavericks would fix it but it did not.
Is this fixable, please?

This seems like a problem with your router. Try forcing your hostname with scutil:
scutil --set HostName yourhostname
Why the number?
The bracketed numbers appear because the same Bonjour/ZeroConf name is being used multiple times on the network. If Bonjour detects a duplicate name, a number is appended to ensure uniqueness.
This does not indicate a serious problem. Resetting network caches and devices should help clear out the now superseded name.
Apple's Bonjour Frequently Asked Questions page discusses this behaviour:
12. What should happen when two devices on the network both use the same service name?
In the rare case where a name collision occurs, your device should add a digit to the end of the name, for example:
"Apple Mac mini (2)"
