    You can wire multiple capacitors in the circuit if you want the gun to shoot faster and further.

    With that capacitor, not very. This isn't a weapon. It is more like a school project.

    Does the capacitor for this have to be from a disposable camera?

    Any capacitor should work. Bear in mind that if you get a capacitor that has a higher charge content, it will be more powerful.

    Will any copper wire work? Or does it specifically have to be magnet wire?

    You should go for enameled wire for efficiency reasons. There are materials to avoid. You are looking for wire with a low resistivity to reduce the amount of heat created.
