Is there a way to quickly mark all emails as read instead of going over each one of them manually ?

Select all the mails you want using Cmd-click (one by one), Shift-click (a range), or Cmd-A (all in mailbox), then either right-click or Control-click and select Mark -> As Read
. This option is also available through the menu: Message -> Mark -> As Read
. The keyboard shortcut ShiftCmdU will also do the same thing.
