Two similar object with different mass falling at the same time and speed.?
Why the heavy one does not fall faster.

for gaining speed acceleration is required.acceleration is provided by a force.the force which provides acceleration to falling bodies is the force of gravity or the gravitational pull.
the speed of any falling object is given by the formula
v=u+gt where u is the initial velocity which is zero for an object falling from rest,v is the velocity after a lapse of time t and g is the acceleration due to gravity which is approximately 10 metre/sec/sec.you will find that the mass of the object or the weight which is nothing but the force with which the earth is pulling it (w=mg) doesn't figure in this formula at all.The momentum of the heavier object will be more as momentum is the product of the mas and the velocity
if at all there is any marginal difference in the speeds it could be attributed to the resistance provided by the atmosphere

The time required for a body to fall depends on its acceleration. Since the fall occurs due to gravity and the acceleration due to gravity is same for all objects irrespective of its mass, all objects fall with same speed.

Force of gravitation between an object and earth = (G * m *M)/R^2, where m is mass of object, M is mass of earth, R is earth's radius and G is a constant.
Also the object is coming down due to F= m * g
Above 2 forces are equal, implying, g is not proportional to mass of the object.
So objects of different mass comes down with the same acceleration.
Now between paper and coin, with same acceleration, coin comes faster because air slows down paper; in vacuum both comes at the same time

Gravity pulls on both the same. But if this were not in a vacuum, the friction of the air would have an effect. But in a vacuum, a rock and a feather would fall at the same speed.

You cannot consider 'objects' as a single item when explaining why gravity doesn't favor heavier items. All items must instead be considered as a large mass of atoms, each experiencing the same 'pull' from gravity. Nomatter how many atoms there are, they are each only considered a single object experiencing the same gravity pull.
