In a vacuum, yes, look up the video on youtube of dropping a feather and hammer on the moon. However, on earth, that is not the case, due to air resistance. The flat paper has more surface area for the air to push back up on, and therefore slows it down more
-- If they're dropped in a place where there is air, then that could be accomplished byeither dropping the paper some time before the book, or from a height much lower thanthe height from which the book is dropped.-- If they're dropped in a place where there is noair, then all you have to do is dropthem at the same time from the same height. Without air, they fall together, and reachthe bottom at the same time.
because it is more lighter than the crumpled one. and its density is much lighter.
The paper has more surface area and therefore more air resistance than the marble does. If you wad up the sheet of paper in a tight ball, you'll see very little difference in the falling speed.
beacause the force of gravity is not stronger on one compared to the other.

Between rock and paper, paper is lighter. However if dropped from same height they do fall at the same speed.
crumbled
The crumbled. It's more like a ball, unlike the 2D paper. And since you can't keep the paper completely folded, It might as well be in 2nd place.

Yes, crumbling something is a physical change. For example, lets say you crumbled up your paper, theoretically, you could always get your completely flat paper back from the crumbled up mess.

The height of a piece of paper folded in half once is half of its original height.
Because a flat piece of paper has a larger surface area and therefore more wind resistance. But in a crumbled piece of paper the wind resistance is less.
beacause the force of gravity is not stronger on one compared to the other.
When you crumple a paper you are decreasing the surface area. The less surface area, the less the wind can stop the paper. it also works because you are putting more weight on one area.
