No, they must be filled (and not with air). The only exception is the silver 12 gram cartridges for pistols and stock class guns.
It depends on the gun and adapter but usually you have to insert it seal first into the area where the pin is (there will be an oring there). Usually you have to screw something in to pierce the seal, but there could be a lever or other device instead. The other method is you unscrew the charger from the gun, drop the co2 cartridge in, and screw it back on.
No. the only full air canisters are 12 gram CO2 cartridges, all others are sold empty under law.
If you are asking about the small 12 gram C02 cartridges, then,"No" they are not reusable. However, larger tanks (like 20 oz) with pin valves on the top are refillable.
