What force slows down things moving through the air?

Friction drag force causes objects to slow down as they move through a fluid, such as air or water. Drag force is especially dependent on the speed of an object.

Which force is present when two objects rub against each other?

Friction is a force that opposes motion. It is present whenever two surfaces rub over each other, such as when you rub your hands together, or when you apply the brakes on a bike or in a car. Friction also prevents an object from starting to move, such as a shoe placed on a ramp.
