Yes, you can use .32 Long cartridges in a .32 Magnum firearm, as the .32 Magnum is designed to accommodate both .32 Long and .32 Magnum rounds. However, the reverse is not true; .32 Magnum rounds should not be used in firearms specifically chambered for .32 Long due to the higher pressure of the Magnum round. Always ensure your firearm is rated for the ammunition you intend to use for safety reasons.

Yes, you can also fire 32 S&W, 32 S&W long, and 32 semi rimmed ACP, and the 32 H & R magnum. This can be found in Wiki. The first answer may have thought you said 357 magnum.
Yes. The .327 Magnum is one of the FEW exceptions to the "do not try this rule". It can fire .327 mag, .32 H&R Mag, .32 Long, and .32 S&W.
The .32 Magnum revolver can fire the .32 S&W revolver cartridge. It cannot safely fire other .32 cartridges, such as .32 ACP (auto) 32-20, 32 Winchester, etc etc.

Yes they are. One of the newer guns, in fact, is the .327 Magnum, which will ALSO fire the .32 Magnum, and the .32 S&W cartridge.
Possible misread of 32 Long. There is no 82 caliber firearm.
Yes
Not without endangering yourself and anyone else in the area. Stay with ammunition designed for the firearm you are shooting.
A .32 S&W Long revolver can fire the .32 S&W Long and the shorter .32 S&W cartridges. It is not compatible with any other .32/6.35mm cartridge.
