Yes, the FMA indicates the capabilities of the aircraft and CAT2 stands for ICAO CAT II minima and Autoland. Unless there is a tech problem of which the autoflight system is not aware. See QRH 5.04. Such as Automatic RA call-out INOP - FMA still reads CAT2 and you can shoot for CAT II minima, but autoland is not allowed.

Any time, but only if you have been trained for manual CAT II landings. Overweight landing is a commander's decision and s/he will decide wheather to do untrained CAT II manual or autoland above max demonstrated LW (there may be more "max" demonstrated weights than the one in my/your manual).
With CAT3 dual you can fly CAT III no dh but also cat II (with catIImin)!
Yes. And also CAT I with autoland (same applies for CAT2 FMA) if some constraints are observed. Unless one of your NDs is gone - you would get CAT3DUAL displayed but the capability is reduced to CAT II + Autoland as per QRH 5.03
So still another question, if you lost your autoland capability and 1AP you could still fly a CATII with manual landing, no? Which capability would then be displayed on the fma?
Hard to tell, there's too many variables in the question.
- For manual landing you need CAT II or better
- For CAT II manual landing specific training is required
- A32S minus 1AP would indicate CAT3SINGLE, system is fail-passive and applicable minimum is ICAO CAT IIIA with automatic roll-out capability
- FMA capability may, or may not depend on the degraded equipment. See QRH 5.04.
