Yes, because with an extra hand they don't need to make a ladder
none of them are the least helpful they all help things move upward except the lever but the most helpful one is the pulley a pulley takes up less space and it goes straight up so u can use less force
Fixed if it weighed as less than you, but a movable pulley wouldn't be helpful here. You'd be best with a pulley with multiple supporting ropes.
Either someone has used a belt dressing that left a residue on the pulley or there is a bearing oil seal leaking in the vicinity of the pulley. A few more details of the pulley's environment would be helpful.
Most bolts turn counterclockwise to come off. Year, make, model and which pulley would be helpful.

A rope, cable, string, or belt can be very helpful.
Yes, a pulley can change the direction of a force. By using a pulley system, a force applied in one direction can be redirected to move in a different direction. This is helpful in many mechanical systems for changing the direction of motion or the orientation of loads.
A simple pulley is a rope (or chain or belt) with one wheel this may be a class 1 or class 2 pulley.For a class 1 pulley, the pulley stationary and the force applied to the rope is in the opposite direction as the movement of the object.For a class 2 pulley, the pulley is attached to the moving object and the force applied to the rope is in the same direction as the motion of the object.A compound pulley, consisting of an arrangement of more than one simple pulley, provides many other possibilities with the direction of force either the same direction or the opposite direction of the motion of the object being moved.
There is a crankshaft pulley, alternator pulley, power steering pump pulley, AC pulley, idler pulley, tensioner pulley, etc.
a coumpound pulley is when there is a fixe pulley and movable pulley working together
