An inclined plane is a sloped flat surface used to break upward or downward movement into smaller more comfortable movements. Although it is not flat stairs are inclined planes with foot holes cut into them.
A wedge is two inclined planes placed back to back. A wedge takes a downward force and breaks it into a sideways force. It can make work easier by breaking the work into smaller increments. Even though it is composed of two things it is not a compound machine because it only uses one machine. Wedges are found in many cutting things like knives.
A screw is a inclined plane wrapped around a cylinder. A screw can makes work easier by turning a small rotation into a much larger driving force. You can find a screw in the screws that hold up your wall.
