A gas is compressed in a cylinder. The number of gas molecules would increase, decrease, or remain the same?

Remain the same. There is no gas added or taken away.

The question is a little ambigous; If you mean taking a fixed quantity of gas (say, 1 cubic meter, for example) at air pressure and compressing it into a cylinder; the number of gas molecules would stay the same (as long the pressure was not high enough to liquify any of the gas). I think the idea they are trying to get across here is that by compressing a gas you are not creating or destroying any molecules; just forcing them closer together.

It depends. The number of molecules total would stay the same but the number of GAS molecules might not. Increased pressure can change gas to a liquid.

It remains the same as the merely squash them together !
