If you mean the standard 12 gram CO2 cartridges, they are not reusable.
Co2 comes out of a bb gun because of the compressed co2 cartridges that are used to propel the bb itself. Additionally, the bb gun that does not use co2 cartridges just doesnt shoot out co2, but air in general.

CO2 pellet guns work by using CO2 for rapid fire, with CO2 the gun does not need to be pumped or recorked after every fire. You can also find spring loaded pellet guns.
They are about the same, depending on the pistol. C02 has a tendency to be a little louder on certain pistols but not much difference.
Pellet guns are more powerful. They are stronger because they use a CO2 Gas, whil BB guns are spring-powered.
please state the make and model. It will make it easier to answer your question.
The Crosman model 150 was made between 1954-1967. It is a .22 cal pellet pistol.
some of them are but most aren't, what kind of gun are you looking at?
CO2 cartridges? It depends on the weapon. Check your user manual. Actual cartridges? Oh god no. Unless you want to have a live round explode in your face.
It's not the best idea. It will eventually ruin the seal.
If you are asking about a "springer firing system" The answer is NO do not dryfire it. When you shoot a single cock springer rifle or gun with a pellet in the chamber, there is a moment where the piston actually slows down just before the pellet is fired down the barrel. If you have no pellet in the chamber the piston slams against the end of the chamber and this will eventually ruin the chamber. Dry firing a Co2 gun will not hurt it. You will just waist Co2.
