It's important to know which country this is in because colour codes vary.
Connect the green wire to the ground terminal, the white wire to the neutral terminal, and the black wire to the hot terminal on the compressor motor. Make sure to follow the manufacturer's instructions and safety guidelines when wiring the power cord to the motor. If in doubt, seek the assistance of a qualified electrician.
To answer this question fully the type of appliance has to be stated and its voltage.
You don't say "turn off" or turn on". Light should be connected black to black and white to white and ground to ground. If you connect white to ground it will work, but you are then using the ground wire for an unintended purpose. Neutral is bonded to Ground at the panel. Current on ground wire could cause ground loops and may cause GFCI to trip if you have them in your house.
You will have to check to make sure. Normally, with 4 wires, the black and red are both power for 220. White for neutral and bare for ground. If you are only using one leg of it, you would use the black, white, bare ones and cap the red one. Someone may have used the 4 strand because they had it or 220 was planned but not done or both the red and black are hot. You should be able to tell in the panel. Do the red and black both connect to separate breakers or to one or is the red not connected?
It seems like you are describing the Red, Black, White and Ground in your electric panel. There is 240 VAC between Black and Red and 120 VAC between Black and White and 120 VAC between Red and White. The electric panel has two busses that supply 120 VAC on alternating breakers in your panel. Essentially, the Red turns into "black" in the panel for all practical purposes. If you have a 240 VAC circuit it essentially takes up to two vertical positions in your electric panel.

No, the white should be approximately zero and the black approximately 110-120, assuming the "bare ground" refers to a bare conductor attached to electrical ground.

The bald-faced hornet is a black and white hornet that you can find hovering close to the ground. These hornets are common across the United States.
If you are connecting 120 volts, you connect the black wire to the breaker, white wire to the neutral bar, and ground wire to the ground bar. If you are connecting 240 volts connect the black & white wires to the breaker, & ground wire to the ground bar.

Wall receptacles are wired in parallel. black to black, white to white, ground to ground.
Yes. Connect Black to Black, White to White and bare ground wires together.
