Air resistance is basically friction between the object on the air- it has to push the air out of the way, and slows down.
No, the air inside a ball does not affect how fast it falls. The rate at which an object falls is determined by gravity and the air resistance it encounters, not the properties of the air contained within the object.
Yes, the area of a parachute directly affects how fast it falls. A larger parachute will create more air resistance, slowing down its descent, while a smaller parachute will fall faster due to less air resistance.
Yes, however, even air affects how fast something falls. The weight of the water is what causes buoyancy (certain materials to float), and and the resistance of water plays a small role - the weight of the water being the larger role - in what causes other materials to fall slower than they would through air. There are actually certain things that are buoyant in the air, like helium. You will notice that if you let all the air out of your lungs, you will fall down through the water at a certain (very slow) speed. That speed is your terminal velocity through water. The terminal velocity of an average sized human through the air is about 55.6 m/s (200 kph or 124 mph). This speed is obviously much higher than the speed at which something falls through water. So water does affect haw fast something falls. "But wait, certain objects appear to fall through the water at the same speed that they fall through the air!" To explain this, water affects how fast something falls - compared to how fast it falls through the air - depending on its density. The object which you're talking about, is actually falling slower through the water, you just can't tell. We see this property in air too, why do you think a pound of feathers falls much slower than a lead weight?
Air resistance acts as a frictional force that opposes the motion of an object falling through the air. The presence of air resistance will slow down the fall of an object, causing it to reach its terminal velocity where the downward force of gravity is balanced by the upward force of air resistance. The larger the surface area and less aerodynamic the shape of the object, the greater the impact of air resistance on its falling speed.
All objects fall at 32 feet per second per second, meaning that every second, they are falling 32 feet per second faster. Air resistance may have a minimal effect but the density of the object will not affect the speed.

If there is a lot of air it will not rot very fast than a small air space.
In air, yes. In vacuum, no.
The factors that affect the speed of an object in free fall with air resistance are the object's mass, the surface area of the object, the density of the air, and the gravitational force acting on the object.
Whether an object falls quickly or slowly basically depends on its mass, and its air resistance. More mass will have the tendency to make things fall faster; more air resistance will have the tendency to slow it down. The air resistance depends, to a great extent, on the object's surface area; however, the shape of the object also plays a role.
Oceans affect climates by slowing the rise and fall of air temperatures. Because water has a high specific heat, it holds heat longer than air.
