.32 caliber. In a semi auto handgun, probably .32 ACP
Pretty much the same as any other revolver or semi-auto.
The Walther PP was made in 5 different calibers- ONE of which was .32 Auto. If the gun is question is a .32, it can shoot .32 auto. If another caliber- no.

Depends entirely on which .32 caliber gun. A small .32 Auto might have an effective range of 25 yards, a long barreled 32-20 revolver 80 yards, and a .32 Winchester rifle 200 yards.

.32 caliber is not enough infromation. Ammunition marked "7.65 Browning", ".32 auto" and ".32 ACP" for practical purposes, are all the same. Do NOT try to use ammo such as ".32 magnum" or ".32 long" as it would be a different round.
Your best bet is to find a gunsmith and ask for help.
Yes- 7.65mm is the metric designation for .32 ACP (Automatic Colt Pistol) which is same as .32 Auto.
