(using squats for the sake of explanation)
The lifter exerts an action force on the weight, which is in the opposite direction to gravity. The lifters shoulders also experience the reaction force (from the weight - otherwise, the weight would pass through the lifter or vice versa). The feet of the lift also experience a reaction force, which, combined with the shoulder-reaction force, is equal to the action force (Newton's Third Law). The feet also experience friction on the floor surface in opposite directions (which cancel out, so the lifter is stationary on the ground) :)

When you drop the apple what are the forces acting on it?
There is the apple's weight (mass * gravity) but there is also the air resistance acting against the object's weight.
Are all forces weights?
No, the other way around: all weights are forces. The word "weight" is used for one specific type of force: the force of attraction due to gravity.
