Most .22 caliber revolvers will hold 6 rounds in the cylinder chambers. Some models from different manufacturers will have a 9 round capacity. I own both.
Up to 9 depending on model.
Probabably 22LR. Have it checked by a gunsmith.
It can.
A .22 revolver takes CARTRIDGES. Which .22 cartridge will depend on what caliber the revolver was made for. A .22 LR can shoot Long Rifle or Short cartridges, and a .22 WMR uses .22 magnum cartridges. They do not interchange. There are a few .22 revolvers that have 2 cylinders, and can shoot either cartridge.
.22 short, long or Long Rifle. .22 Long Rifle is available just about anywhere and can be shot in your revolver.

It fires .22 Long Rifle bullets, and leaves behind shell casings when you eject them from the cylinder after firing.
IF the revolver is marked ".22 LR" yes. If it is marked ".22 WMR" or .22 Mag" or " .22 WRF", then NO.
15,17 or 22 rounds depending on which 22 rimfire ammuntion is used.
Depends on the model.
.22 Long Rifle bullets...
No. .22mag. bullets are too long, and they aren't heel-type bullets
