Terminal velocity: 75 m/s
Air resistance: 750 N
Force due to gravity: 750 N
Air resistance increases by 100 N with every 10 m/s increase in velocity.

Terminal velocity is the term for the maximum rate of decent of a 'free falling' object subject to only gravity and the affects of our atmosphere. Any object in the air may have other forces acting upon it to speed it up or slow it down. A down draft would speed up the sky diver but he would not realize this because his speed relative to the air in which he is falling is the same as if he is falling in still air. He would, however, hit the ground harder or need to deploy his chute quicker to avoid that. The human body could achieve a rather high speed (well beyond normal terminal velocity) without 'coming apart', if that is what you are asking. Pilots eject into air streams while flying at several hundred knots with usually only minor injuries. It's not the fall that kills you, either.... It's that sudden stop.
Murdo, kudos! excellent followup and absolutely correct.

Assuming some disturbance made it possible to temporarily exceed terminal velocity, then when the disturbance disappeared then the sky diver would decelerate back to terminal velocity, and his excess velocity would decay exponentially with time.
Air resistance does not increase in a linear fashion as you suggest. An increase from 75 to 85 m/s would increase drag by 213.3N = (750 * (85/75)2) -750

That diver will accelerate to the new terminal velocity because of the increased force. Then quickly decelerate back to the original terminal velocity as soon as the extra force is gone.

You cannot exceed Terminal Verlocity, Terminal Verlocity is the maximum speed an object can achive during free fall, an object or persons terminal verlocity can be incresed by reducing air resistance.

His acceleration becomes 0 and he maintains current velocity of 75 m/s

You can't exceed terminal velocity. Once you have reached terminal velocity, it doesn't matter how much faster you are going, you are still going to be dead when you hit.
