A screw is the simple machine which holds two boards together. In this case it is not acting as a machine though.

No. Gears are a type of simple machine. Combined with another simple machine, it would then make a compound machine.
That would be a wedge.
It's a tool
That isn't possible, not with a simple machine and not with a complicated machine, since otherwise, conservation of energy would be violated.

a complex machine would be a car, but a simple machine would be a wheel and axle. an example of a wheel and axle would be a steering wheel
That would be a lever.

Yes, a hovercraft is considered a simple machine because it uses principles of physics like air pressure to generate lift and propel itself forward. It does not have complex mechanisms like gears or engines.
This would be a compound machine. An example would be a winch, which is usually a pulley/fulcrum combo.
A protractor is not considered a simple machine. It is a measuring tool used to measure angles.
