Yes, as the skydiver gains momentum, the Earth also experiences a change in momentum, but due to the large difference in masses between the Earth and the skydiver, the effect on the Earth's momentum is negligible. The system of the Earth and skydiver together will conserve momentum overall, with any change in the skydiver's momentum being balanced by an equal and opposite change in the Earth's momentum.
The maximum weight for a person to skydive is 220 pounds.
gravity
500 N is pressumably the weight, due to gravity. "Terminal velocity" means that the forces are in balance; the total force acting on the skydiver are zero. This is only possible if there is a 500 N force due to friction, to counteract the weight.
When a skydiver reaches terminal velocity, the force of weight acting downwards on the skydiver is equal to the force of drag acting upwards. This means that there is no net force acting on the skydiver, resulting in a constant velocity rather than acceleration.

If you're telling us that the skydiver weighs 845 newtons, then that's the magnitudeof the forces of gravity between him and the Earth whenever he's near the Earth.
If a skier is in a jump, then a skier and skydiver is pretty much the same thing. In general though, a skydiver has only air resistance, the skier has air resistance and friction with the ski-snow, so the skydiver has an edge on speed.
Europa's weight is about 13.5% of Earth's weight. This is because Europa has a much lower mass and gravity compared to Earth.
A skydiver typically falls at a speed of about 120 mph (193 km/h) during freefall due to gravity. This speed is known as terminal velocity, when the force of air resistance balances the force of gravity acting on the skydiver.
