Yes.
Newton's Third Law applies everywhere.
Yes, it does. They use Newton's third law, because a propeller pulls or pushes you forward by moving a mass of air or water behind you away from the direction of acceleration.

Yes.
Yes. Newtons three laws of physics apply to everything in our universe. Only when you study molecular structure and the early formation of the universe do you have to use Einstein's Theories.
Tell us the situation, and we'll apply Newton's Laws.
85 newtons, up . =================== Nope. The force of gravity is 35 newtons, directed down. The force of your mighty out-stretched arm is 50 newtons, directed up. The net force on the book is 15 newtons directed up, so that's the direction in which the book accelerates. (At 15/35 = 3/7 of a 'G' .) Exactly the same analysis as you'd apply to a rocket launch.
When you apply a force there is always an equal and opposite force applied to resist change as newtons first and third law state. The force the object applies to resist change is the resistance force. An example is the force supplied by the sidewalk when you walk on it.
Any force greater than 980 newtons.
