When you drop a ball from, say, 3 metres, it will bounce back to roughly 2 metres.
As long as the tennis ball is not thrust downward, yes, the tennis ball will bounce back to the same proportion of its original height, no matter how far it's dropped, as long as the height is small enough that air resistance can be ignored. The ball will eventually come to rest due to this air resistance.
The higher the height the ball is dropped from, the higher the height it will bounce to.
The brick and the tennis ball might land at the same time, but the leaf will fall last.
Yes - the greater the height an item dropped the resulting bounce is higher

Gravity, air resistance, the material of the ball, and the height from which it was dropped initially.
yes
It all depends on the height the ball has been dropped and the weight of the ball.
Yes. It make it bounce higher because without air it is flat so it won't bounce at all
