You're fishing for "air resistance" but your description isn't correct.
Air resistance doesn't "slow" a falling object. Once the object has
built up to some particular speed of fall, air resistance prevents it
from falling any faster.
Slidig Friction is the kind of friction.
static friction
Static Friction
Friction refers to the resistance that one surface or object encounters when moving over another. The kind of friction that sliding objects experience is sliding friction.
Gravity: The pull of two objects on each other.Inertia: Basically something that slows any kind of acceleration or deceleration on a moving object.Yup, those two are the main forces that act on a falling object.

friction and any other kind of force that is in the opposite direction
That's the 'kinetic' kind..

Yes, in general friction can occur in a vacuum, but the only kind of friction that doesn't occur in a vacuum is, of course, air friction. There is no drag force on an object falling in a vacuum.

Friction does not move things. Friction is the force that opposes motion between two objects that are touching. Not enough friction allows for things to move, depending on what kind of friction; the less force it has.
Air pressure. For instance, in a complete vacuum, a feather would fall as fast as a lump of lead.
