The amperage rating of any wire or conductor is determined by its size or gauge. It has nothing to do with whether it is a two, three or four conductor wire. For example, in basic residential wiring, a 14 gauge wire is rated at 15 amps, a 12 gauge wire is rated at 20 amps, a # 10 is rated for 30A and so forth.
That is 10 amp wire.

The ampacity or amp rating of all wire is rated by the size of the wire. NM (non-metallic sheathing) wire is no different. In household wiring 14 gauge wire must go on a 15 amp breaker/ 12 gauge goes on a 20 A and 10 gauge goes on a 30 Amp.
Yes you can. That being said the different wire size that is to be used can not have a smaller current capacity than the breaker that is supplying that circuit. In other words the wire size that is added to the circuit has to be larger not smaller. For example a 20 amp breaker can have a #12 at 20 amp rating, #10 at 30 amp rating or a #8 at 40 amp rating added to the circuit but not a #14 which is only rated at 15 amps. Using 15 amp wire on a 20 amp breaker could overload the capacity of the #14 wire which is rated for a maximum of 15 amps.
250 amps maximum.
That is 10 amp wire.

A #3 copper wire with an insulation rating of 75 or 90 degrees C is rated at 100 and 110 amps consecutively.

Wire size is rated by Amperes of current. You did not mention the wire size of the aluminum wire, so there is no way to answer your question. The voltage rating is more a rating of how good the insulation around the wire is.
A 3/0 copper conductor with an insulation rating of 90 degrees C is rated at 225 amps.
