The Air Source Adapter or ASA is the part of the marker where the propellant tank is screw in, and gas is released through the opening of the tank valve. Simple ASA's simply open the pin valve by having another stationary pin or bump press against the valve pin as its screwed in. More complex ASA's allow the player to adjust the activation pin through another means, so that the tank can be screw in and out without pressure and then opened by a screw or lever motion. Most ASA's also have a "bleed out" hole for excess gas to escape when the tank is unscrewed.
the ASA (air source adaptor) can typically be swapped out for a aftermarket one, there are a few markers out there that the ASA is also the regulator for the marker and these can not be changed out typically
Fifty caliber, but it is more of a toy than a paintball gun.
It depends on the gun, but "both" is an acceptable answer.
The sizes 9 oz and all the way up to 20 oz can be used for paintball gun. Some of the paintball guns are supposed to be used by the larger tanks. So the size of tank depends on your paintball gun.

On a paintball gun C02, or High pressure air is necessary. It is compressed air that, when the trigger is pulled and the marker fires, propels the paintball out of the barrel.

Have a degree in chemistry. Do not put anything in your gun besides air-tool lubricant (for mechanical guns), or actual paintball lube.
No, you should use only paintball specific of air tool lubricant.
The purpose of a paintball gun is to fire paintball pellets, to mark opponents in the game of paintball.
O-rings are used in paintball guns to seal off spaces, ensuring that air does not leak from the gun. You typically find an o-ring wherever two pieces of metal connect and air passes through. O-rings are a vital part of the paintball gun but periodically need to be replaced.
