You need 1 wire per prong of your outlet, regardless of voltage! (This includes counting the ground wire).
If you have a NEMA 6 receptacle, it is 3 wires (2 hots and a ground). If you have a NEMA 14, the 4 wires are 2 hots, a neutral, and a ground. If you have a NEMA 15, it is 3 hots and a ground (a 3 phase receptacle).

It depends. Single phase needs 3, 2 hot 1 neutral. 2 Phase needs 3 also. If you are wiring a trailer house you need 4 the 4th wire has to be an earth ground. I suggest you get a book on basic wiring.

It depends on what you need to supply power to. If it is going to a dryer the dryer motor runs on 110V. and the heater runs on 220V.. In order to accomplish this three wires plus ground (10/3)are needed. If it is for something that only requires the 220V(208V minimum) such as a water heater or air conditioner you need two wires with ground. The size of the wire depends on the current(amperage) draw of that device.

It depends on what phase it is. Single phase requires 3 wires, 2 hot wires or "legs" (normally black in color) and a ground wire (normally green in color or solid copper wire). 3 phase requires 4 wires, 3 hot wires or "legs" and a ground wire.

nothing personal, but, if you gotta ask ,you should call an electrician.
everybody has great answers, but, this is not a job for an amatuer.
