No is my guess i think its false but it might be wrong.^^'
because water is dencer than air

The momentum of the diver with the gravity against the thinner air in the altitude and the position of your body cause you to slow down your fall.
Gravity
No. It will accelerate the diver downward only.
Yes
Gravity always acts as a pair of forces, not as one single force. The strength of the forces depends on both masses, not just one of them. The forces of gravity attract the diver toward the earth and the earth toward the diver. The forces are equal in both directions. If the diver weighs 150 pounds on earth, then the earth weighs 150 pounds on the diver. The diver accelerates toward the center of the earth with an acceleration equal to (weight)/(diver's mass), and the earth accelerates toward the diver with an acceleration equal to (weight)/(earth's mass). Has that helped, or just confused the issue further ?
Yes!
64.9559kg if the gravity acceleration is 1
The diver and the Earth actually pull on each other with the same force. But with Force = mass x acceleration, rearrange that to: Acceleration = Force / mass. With such a large mass, the Earth is accelerated by a miniscule amount. Compared to the acceleration of the diver, it is not noticed.
the diver
Gravity doesn't change.
