This is a classic question.
In a vacuum, both the the coin and the crumpled paper fall at the same rate due to the absence of air resistance.(Their acceleration being the same)
However, in air, the relative air resistance on the paper is greater than on the coin.(relative, because the coin and the paper do not have the same mass, so the proportion of air resistance as compared to weight is the one relevant) So the acceleration of the paper decreases to zero more rapidly than the coin.(it will decrease to zero provided the objects are released from a sufficiently high point from the earth's surface).
Thus, the coin will fall faster in air.
Aerodynamics
Assuming that both pieces of paper weigh the same, a crumpled piece falls faster in the presence of an atmosphere. In a vacuum, they would fall at the same speed due to the lack of wind resistence.
The ball presents less Surface Area to the air than a flat sheet. So, there is less air resistance when a thin piece of paper is crumpled into a ball.
The flat paper has more surface area, allowing it to catch more air and float. The crumpled paper on the other hand, does not, because it doesn't have as much surface area to spread the air out.
The crumpled paper has less air resistance.

The crumpled paper has less air resistance.
Because there is less surface area on the crumbled piece of paper, there is less area upon which the force of friction (air resistance) may act. There is more surface area on the normal piece of paper, which allows friction to act over a greater area on the paper. More air resistance causes the flat piece to fall slower.
False, the gravity on the sheet of paper is the same regardless of its shape. However the crumpled sheet has less air resistance than the flat sheet allowing it to fall faster.
A flat piece of paper has a larger surface area, creating friction with the air, or more air resistance. There is more air surrounding the piece of paper, and this slows it down. A crumpled piece of paper has less surface area to create friction, meaning less air resistance. This causes it to fall faster.
The flat paper has more surface area, allowing it to catch more air and float. The crumpled paper on the other hand, does not, because it doesn't have as much surface area to spread the air out.
Because when the sheet of paper is flat, it acts like a parachute, and collects much more air resistance. The balled-up piece of paper has much less surface area, so can collect much less air resistance, making it fall faster.
because it is more lighter than the crumpled one. and its density is much lighter.
It accelerates faster because it has less air resistance.
