What exactly pulling the man up/down in rocket?

Suppose man is traveling in a rocket. if rocket goes up, man feels someone thrusting him down, vice versa.

Floor of rocket or lift pushes him up.

There are two answers in your question depending in which frame of reference we ll answer.

1. In the accelerating frame of reference of the rocket, there is a fictitious force that presses the man down. Maybe its not the right time to be introduced to fictitious forces but you can google about them and read the article on wikipedia. https://en.wikipedia.org/wiki/Fictitious_force
2. In the inertial non accelerating frame of reference of the ground there is the force from the floor that accelerates the person. Hence due to Newton's 3rd law the person exerts an opposite and equal force to the floor.

If there was a hole in the bottom of the rocket, the rocket would go up without the man. He'd be left on the ground.

@PeroK post #4 might seem funny but he says a lot, its the force from the floor/seat that is responsible for this effect. Forget my post about fictitious forces.

The gravitational force on the pilot and the force from the seat and seatbelt are the only relevant forces here. But you feel the thrust even when accelerating somewhere in space where there's no more gravitational force to any particular direction.
