Well it really depends on several factors that have to be just right in order for two objects to fall at the same speed or rate.
The three main factors needed to calculate the speed at which two objects fall are Time(t) Velocity(v) and Rate of Acceleration.
The formula used to calculate is:
Acceleration= v-u/t (the v-u is change in velocity)
All objects fall at the same rate, which is the acceleration due to gravity, when air resistance can be cancelled out. Galileo proved this phenomenon in the 17th century by dropping balls of the same material but different masses from the top of the Leaning Tower of Pisa. They landed at the same time. The size of the objects does not matter. A 1kg rock will fall at the same rate as a 10kg rock and, if started at the same height, will land at the exact same time. Even a feather and a ball-bearing will fall at the same rate and land at the same time in a vacuum, where there is no air resistance.

In the absence of an atmosphere, all objects will fall with the same acceleration. If two objects of different mass begin with zero velocity and are released at the same time, they will fall at the same speed.
A marble and a bowling ball fall at the same acceleration speed. Anything with the exact same shape falls at the same velocity. 10 meters/s/s
In the absence of air, everything falls with the same acceleration, and reaches the same speed in the same amount of time after being dropped. If things fall through air, though, this isn't true.
That depends. 10 lbs. of bricks will fall at the same speed as 10 lbs. of feathers. Meanwhile, a cinderblock will fall far faster than a single feather. If two things are the same weight, they will usually fall at the same speed. If two things are different weights, they will fall at different speeds. ^ This only takes effect when wind resistance is NOT added.
Quarters and feathers would only fall at the same speed in a vacuum. In air, the quarter would fall faster, as it has less air resistance.
No lighter things do not fall faster than heavier things. In a vacuum they will fall at the same speed. Normally the heavier thing will fall down faster because of its weight. Sometimes the lighter thing falls faster depending on the air resistance.

both will fall at the same time
iT DEPENDS IF THE BALL IS LIGHT THE LIGTER MOSTLIKLEY TO HAVE THE SAME SPEED.

In a vacuum sealed room, yes, they can. If not, then without properly balanced air resistence, no. The only reason objects fall at different speeds is because of air resistence/terminal velocity, things of that nature. When dealing with air, and etc... if you want them to fall at the same speed, they have to have the same air resistence (a combination of space taken up, and mass.) So yes, they could fall at the same speed, but the yarn would probably have to be coiled extremely tightly.
No lighter things do not fall faster than heavier things. In a vacuum they will fall at the same speed. Normally the heavier thing will fall down faster because of its weight. Sometimes the lighter thing falls faster depending on the air resistance.
Air resistance of an object can slow its fall. If every object had the same resistance, everything would fall at the same speed.
In a vacuum.
