[Claudio]

On ubuntu application bar I see multiple red dots like when I've many instances of the same app but instead of five(see the annexed image) I've only two.

My ubuntu system info:

It sounds like Android Studio has some hidden windows which are not being handled correctly by Ubuntu Dock.

This statement:
*there are also some others problems: if I've a simulator launched(android simulator) I can't launch a new instance of the Studio. Example: open AS, run Simultaor, close AS(the simulator remain active) -> click on icon -> no choice allowed (not possible to run a new AS instance) *

Is incorrect. It is possible to launch a new instance of AS. My mistake

Sounds like this might be related to bug 1932328. You will be able to test that fix after mutter 40.6 is available in updates for Ubuntu 21.10 (not yet).
