You need to use .32 S&W ammo, which may be hard to find.
No.
I have never seen nor heard of a revolver airsoft pistol with non reusable shells. You should have no problems reusing them.
yes any gun that shoots bullets has shells. A revolver doesn't 'dump' the shells out, they have to be removed by the shooter before it can be reloaded. It is a bit easier to keep track of the empty brass and avoid leaving evidence behind.
No, they can not, do not attempt to mix real ammunition in airsoft guns.
No. But there are revolvers made to shoot .410 shells that also fire .45 Colt cartridges,
If a shot has a 3inch chamber it will also shoot - 2 3/4 inch shells..
The weapon may not be a semi or an automatic one.
You need a gunsmith.

No. will handle 2 9/16 old shells or 2 3/34 modern regular pressure shells.
A pump or auto suppose to be plugged so no more than 2 shells in magazine and 1 in chamber
Yes.
