A pistol rated to fire .38 +P ammunition is still going to be a .38 Special pistol, and can use regular .38 Special ammunition. .357 Magnum revolvers are also capable of chambering and firing .38 Special loads - regular, +P, and +P+ included.
No such caliber as .32 Special. Use the caliber of ammo marked on the gun.

If you mean can you fire non plus P ammo in a gun rated for plus P, yes, you can safely do that as long as it is the correct caliber.
No, and you shouldn't even use. 38 Special ammo in it, either. If it was made in the 1800s, it was probably chambered in .38 Long Colt, and that is the only ammo which is compatible with that revolver.
.38 special Stay away from the "+P" ammo
Yes. The 44 magnum can fire 44 special ammo in the same way a .357 magnum can use .38 Special.
yes, but better to use standard ammo. +P ammo shakes the pistol a lot.
The strongest ammo available for .38 (and for most any other caliber) is plus-P-plus. However, .38 special is not particularly effective against bears.
You can use 38 special.
Yes, +P is actually a higher pressure so using the lower pressure regular loads may actually extend its life some.
no
Yes. Shooting a lot will accelerate wear on the gun, but occasional use is OK.
