No, it must be screwed. - But there are many varieties of excellent concrete board now. -
NO, you shouldn't do that. There are many fibre/concrete products that are way better.
If one side of the drywall is green, it is actually green board. Green board is made with concrete, and is intended for high humidity areas. It will not mold or mildew the same way normal drywall will in moist conditions.
solid, cemented
NO. -Concrete may be a 'dry' wall, however it is NOT Drywall.
If the drywall is directly onto the concrete, drill into the concrete and use a shield and screw or there is a concrete screw called Tapcon that screws directly into the concrete without a shield and holds much better. If the drywall is on furring strips, either mount the banister on the strips or go through the strips into the concrete.
You use standard 1/2 inch drywall .

Yes, it is as toxic to animals as it is to humans.

Yes it Does.
If you want to do a really good, lasting job, use concrete/fibre board (Green board) instead of drywall. It comes in 30x60 sheets, about the same cost as drywall, easy to work with , totally water resistant and excellent for tiling. About 4-5 kinds available, Rona and HD each have 2-3 types.
You are supposed to fur it out first. - That means a thin wood frame, usually 1x4 on the concrete FIRST. - It is not customary to apply drywall directly to a concrete basement wall.
