It is an inclined plane and some sort of pulley
No. A pulley is a simple machine in its own right.
No, that's one of the other simple machines.
The inclined plane lessens the amount of force you need to lift an object like the other simple machine, the pulley but moves the object in a slant motion instead of the up and down motion of the pulley,
A single pulley simply changes the direction of the force. A block and tackle or multiple pulleys can offer a mechanical advantage - same as an inclined plane. For the same mechanical advantage, a pulley system may be better because of lower friction.
