Use what is called bell wire or thermostat wire.
You need to look at the regulations that apply in your country. If in doubt, use a neutral wire of the same size as the live wire or wires.
The size breaker you use is determined by the size wire used in the circuit. If you use AWG #12/2 wire then use a 20 amp breaker. If you use AWG # 14/2 then use a 15 amp breaker.

A 100 amp service requires that you use AWG 4 copper wire or AWG 2 aluminum wire.
The wire will conduct as usual but remember that wires smaller that 1/0 are not allowed to be paralleled according to the electrical code.
No, it is not safe to parallel 10 gauge wire for a 60-amp circuit. You should use a wire size that is rated for the amperage of the circuit to ensure it can handle the load safely and prevent overheating. In this case, you should use a minimum of 6 gauge wire for a 60-amp circuit.

10-32 unf-2a <<>> The wire size does not need to be calculated. Use a wire terminal end that crimps to the wire. These terminal end come in various wire sizes and bolt hole sizes. Pick the correct end for the wire size you are using and then in that wire size range, pick the correct bolt hole size that fits the bolt.
Use AWG #6 wire.

You will need to use #8 wire.
Use 8 gauge wire.
