A feather and a stone do not fall at the same rate. The feather falls at a slower rate because a feather is subject to the effects of air resistance (it's air resistance to weight ratio is small. A stone has a large air resistance to weight ratio) . The feather may also be subject to blowing winds. Think of 2 pieces of wood. One is 10 lbs and is a sheet, the other is 5 lbs and a block. The weight does not change how fast they fall but the resistance to the air does and so the 10lb sheet of wood takes longer to fall.
When you drop a feather, the two main forces that will affect it are gravity, which pulls the feather downward towards the ground, and air resistance, which pushes against the feather as it falls, slowing its descent.
For a feather and a ball to fall at the same rate in a vacuum, they need to experience the same gravitational force acting on them. This means there is no air resistance to slow down the feather, and they can both accelerate similarly due to gravity.
As a feather falls, the force of gravity acts upon it pulling it downwards towards the ground. Additionally, air resistance creates an upward force that slows the feather's descent. The net force between gravity and air resistance determines the feather's acceleration and speed as it falls.
In a vacuum, a feather and a piece of paper would fall at the same rate due to gravity. However, in Earth's atmosphere, the feather would fall more slowly due to air resistance.
When a feather falls through the air, the main forces acting upon it are gravity pulling it downward and air resistance pushing against it in the opposite direction. These forces cause the feather to accelerate towards the ground until it reaches a terminal velocity when the air resistance equals the force of gravity.

Unless you drop the feather in a vacuum, air resistance will be significant, so any acceleration (change in velocity) will not be due solely to gravity.
Air resistance(AKA drag), gravity

In a vacuum, a feather and a quarter would fall at the same rate due to gravity's influence. However, in normal conditions with air resistance, the feather falls slower since it has a larger surface area, creating more air resistance.
In a vacuum, where air resistance does not exist, objects of different masses will fall at the same rate due to gravity. This is because all objects are subject to the same gravitational acceleration. On the moon, with no atmosphere to create air resistance, both the lead weight and the feather will experience the same gravitational pull and fall at the same rate, leading them to land on the ground simultaneously.
In a vacuum, where there is no air resistance, both a feather and a hammer would fall and hit the ground at the same time due to gravity affecting them equally. However, in the presence of air, the feather experiences more air resistance than the hammer, causing it to fall slower.
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.
A brick falls faster than a feather due to differences in mass and air resistance. The brick has more mass, so gravity exerts a greater force on it, causing it to accelerate faster. Additionally, the feather experiences more air resistance due to its larger surface area, slowing its descent.
