-5 Newtons, or 5 newtons to the left, if this is kinetic friction we are speaking of. If it is static friction, then the box will not move, and since net force=mass times acceleration, and acceleration is zero, the net force will also be zero.
The 15N force to the left would cancel out 15N of the force to the right, so the net force would be 35-15N, or 20N to the right.
The net force applied is 4N upward ( 39-35); that means the box is accelerating upward as you lift it.

The buoyant force is the weight of the displaced water. That's 15n, and it points upward. That upward force combines with the downward 20n due to gravity. The net force on the object is 5n downward.

"Terminal velocity" means that it no longer accelerates; forces are in balance. This is only possible if the upward force is also 50 N. (The "50 N weight" represents the downward force of gravity.)

An object on the Moon's surface weighs 16.55% as much as the same object weighs when it's on the Earth's surface. The fraction is roughly 1/6.
