The penny will land first, because the feather displaces the air. That is also why a boat floats, it displaces enough water underneath it that the displaced water pushes up keeping the boat afloat.
Both the feather and the hammer will hit the ground at the same time when dropped from the same height in a vacuum. This is due to the principle of gravity, which accelerates all objects at the same rate regardless of their mass.
In the absence of air resistance, the penny and feather will fall at the same speed relative to each other. This is due to the acceleration due to gravity being the same for both objects, regardless of their mass.
In the absence of air resistance, both the penny and feather will fall at the same rate and hit the ground at the same time, regardless of their mass. This is because gravity accelerates all objects at the same rate in a vacuum.
In the absence of air resistance, both the feather and the penny would hit the bottom of the tube at the same time. This is because in a vacuum, all objects fall at the same rate due to gravity.
There are many factors that can affect the time for these objects to drop. The height at which each object is dropped is a factor since the height is proportional to time. if the height at which these objects are dropped are the same, then the time for them to drop to the floor is the same. Since the acceleration due to gravity at sea level is 9.81 m/s^2 for all objects no matter the mass, both objects will accelerate at the same rate which means they will reach the floor at the same rate. All in all, both the pencil and the penny will hit the ground at the same time.
If there was no air resistance and a feather and a penny were dropped from the same height they would both pick up speed by the same amount and they would hit the ground at the same speed and at the same time.

Yes
They wouldn't land at the same time. the rock will land first and quickly because a rock have bigger mass than a feather. A feather is very light, if you ever tried to drop it from some height you could see that it takes very long time to land and it might go away to another place too.
as done in Galileo's experiment when he dropped a large rock and a feather from a tall tower both hit the ground at the same moment when dropped from the same height.

both reaches the ground at the same time because in the moon there occurs free fall.

No, a feather and a nail would not reach the ground at the same time if dropped at the same height in a vacuum. This is because the feather experiences more air resistance, slowing its fall compared to the nail which falls faster due to its higher mass.
Purely air resistance, the feather floats on the air. The mass is irrelevant. If a penny was dropped at the same time as a brick (ignoring wind resistance) both would hit the ground at the same time. Look up Galileo's tower of Pisa experiment. http://en.wikipedia.org/wiki/Galileo%27s_Leaning_Tower_of_Pisa_experiment This also includes a video of a feather and a hammer being dropped on the moon (where there is no air). Both hit the ground together.
