1. Pulley helps to pull things up easily, usually used to lift things or to transformed heavy things.
2. Lever helps to affect the effort, or force, needed to do a certain amount of work, and are used to lift heavy objects.
3. Wedge helps to separate two objects or portions of an object, lift up an object, or hold an object in place.
4. Inclined Plane is used as an aid for raising or lowering a load. By the way Wedge is also a kind of Inclined Plane.
5. Screw are to hold objects together — such as wood — and to position objects.
6. Wheel & Axle consists of a wheel attached to a smaller axle so that these two parts rotate together in which a force is transferred from one to the other.
