In residential wiring applications the most used is 14 gauge wire for light switches as long as the circuit breaker or the fuse is 15A. If your lighting circuit is on a 20A fuse/circuit breaker then you need to use 12 gauge wire
That depends on the light and the amount of amperage the fixture/bulb is calling for. In a household you would find #14 or #12 gauge wire for lighting fixtures. In some commercial facilities you may find #10 guage wire being used, a good example of that would be parking lot fixtures.
Wire gauges are defined in such a way that the lower the gauge, the thicker the wire. So, 8 gauge wire is thicker than 10 gauge wire.
The most common wire ran in 120v residential is NM (Non-metallic) sheathed wire such as the brand Romex. 14 gauge wire generally has a white sheathing and can be used on 15 amp circuits such as lighting. 12 gauge wire is thicker, generally having a yellow sheathing and can be used on 20 amp circuits such as those serving receptacles. Considering future demands, 12 gauge wire should be used. Under no circumstances should you ever use 14 gauge wire on a 20 amp circuit.
Yes, you splice a small length of 16 gauge wire to 18 gauge wire for a repair.
Yes. In the US at least.
Wire gauge is used to determine the size wire needed to carry the correct amount of current for the job. It must be sized appropriately for the current in the circuit you are building.
The minimum size wire that engineers spec for industrial and commercial installations is #12 and it usually is stranded not solid wire.
Eaves, electrical outlets, electrical wire, elevator and escalator are building materials.
The wire gauge in thin headphone cables is quite small. I have read of people rewiring their headphones using 12 Gauge wire. There are commercial cables that use 11 gauge. The thicker the wire the less the resistance up to a point. Many headphones use 22 or 24 gauge and it seems to work OK.

The size of the wire is stated by its gauge under American Wire Gauge. Six gauge wire is size 6 AWG.

Yes, the smaller gauge number, the larger the wire is.
