ONLY if you can run a single wire along side the 2-wires. If not, running a 3rd by itself will cause the magnetic field of the wire to overheat (when they're run together, the magnetic fields cancel each other out).

Short answer: Probably not.

You cannot run a separte wire all by itself if the 8-2 is in a cable assembly. It isn't allowed by code. Technically you could run 8-2 cable, and then a separate #8 within a conduit, overheating will not occur and the wires do not cancell each other out when considering magnetic fields. It is however true that Phase A and Phase B have completely opposite magnetic fields, but overheating still occurs, this is why wires are derated when they are all run in the same conduit.

It is more accurate, a 4 wire is more accurate than 3 wire and 3 wire is more accurate than 2 wire.

The only way to change a 14-2 wire into a 14-3 wire is to physically remove the 14-2 and replace it with a 14-3.

put a resistance in one of the wire connecting.....put around 2 to 3 ohm resistance to obtain 3 v fron 6 v.....

A 2-pole wire will not work on a 3-pole plug. You will need to use a 3-pole wire on a 3-pole plug.

Answer for USA, Canada and countries running a 60 Hz power supply service. Yes, but you will need to change the wire from a 2 wire cable to a 3 wire cable. This allows the neutral to be brought out to the load.
