No, the National Electrical Code book (US) limits the current on a #12 AWG to 20 amps.
Yes, you can. It will be fully protected as it can actually handle a 30 amp breaker.
yesAnother (corrected) answer.NO! The circuit breaker is there to protect the wiring from overheating. It wouldn't matter where on the circuit you decided to put the 14 gauge wire, you would need to change the breaker to 15 Amp if you did that. Using 14 gauge wire on a 20 amp circuit is a fire hazard and contrary to UBC. Contact your local building and zoning department to verify.
If your question is can you use a #6 flexible SOOW cord and put a 30 amp plug on it, then yes. The breaker that feeds the receptacle that the cord will plug into can be no larger than a 30 amp breaker. What limits the cord capacity to 30 amps is the ratings of the plug on the end of the cord.
NO! The circuit is being overloaded. Danger of fire will result from just changing the size of the fuse or breaker. A 30 amp breaker may be used with #10 wiring. #10 is rated for 30 amps. I would be hesitant to do this if the tripping problem is something new though.
No, they each need their own breaker of the right amp. Neither of them would cause the breaker to trip if there was a problem.

Its a safety thing. 20amps on that thin of wire will heat the wire up too much. Its a fact; not a story. 14 amp wire is not ok to put on a 20 amp rated device!!!! your wire will burn before the breaker will trip and will start a fire!!!!
Not legally because the rating of the 30 amp receptacle would have a 50 amp breaker ahead of it. If you reduced the feed breaker to 30 amps and still use the #6 wire, this would be within the electrical code rules.

For most apps, the max amps for 16 ga is 25A, so yes.

A 32 amp fixture can not be fed from a 20 amp breaker as the breaker will trip every time.

The fuse is matched to the size wire in the circuit the breaker/fuse it is protecting. For instance, a 20 amp breaker/fuse is used in combination with AWG 12/2 wire. A 15 amp breaker/fuse would be used with AWG 14/2 wire. If there is too much current flow in the circuit caused by either overloading the circuit or by a short in the wires the wiring would overheat and catch fire if not for the breaker/fuse. The breaker/fuse is designed to detect this and to trip or blow and shut off all power flowing to that circuit and prevent a fire. This is why you should never install the wrong size fuse. Put a 20 amp fuse on a 15 amp circuit and it would not protect the circuit as it should.
The gauge of wire is referenced to the capacity of a wire to carry amperage and has nothing to do with the voltage. The voltage of a wire is determined by the type of insulation that surrounds the wire. The size of the wire is determined by the amperage of the load and the distance from the supply.
I would use 12-2 with ground (Black, White, Bare). and use the 20 amp breaker. You could use 14-2 with ground and use a 15 amp breaker. It depends and what you are putting in the garage. We are also required by code to put GFCI outlets in garages. If you are putting the wire in the ground you need to use 12-2UF or 14.2UF which is made to be buried underground.
