The frictional force that opposes the movement of an object that falls through the air is air resistance, or drag.
Yes
Friction.
the amount of air resistance on an object depends on the size, shape, and speed of the object. Air resistance is the force that opposes the motion of objects through air.
The force that opposes a downward force on an object would be called the "normal force". For example, it is as a result of the normal force that people do not fall though the ground the same way that they fall through the air.
Friction .
Viscosity opposes the motion of an object through liquid.
friction can slow down the object or make it stop. it can also cause the object to create heat.
It always opposes movement and slows things down or stops them moving altogether.
Friction is a force that opposes all movement to slow down a moving object.

Nothing is opposing an object falling to earth. Gravity is causing an object to fall back to earth which is opposing the object from leaving earht. If anything the force that opposes gravity is the force at which an object is projected.
Air resistance is the air having to move around the object traveling through it. It is complex. It has as an after product, the movement creates vorticies of air. Air swirling around after the object has passed. It can be dangerous. A small plane landing after big one encounter this turbulence and can get into trouble. Air slows any object traveling through it.
