inertia
Newtons 2nd law of motion states:
An object in motion will stay in motion, and an object out of motion will stay out of motion, unless met with an unbalanced force.
No, centrifugal force is the force that causes objects in rotation to move away form the center of rotation. The force that keeps objects moving in circular motion is called "centripetal force".

inertia
it usually does, but if the force is balanced, it will not change the object's motion

Friction is the force that opposes motion between two objects.
Orbits sould be circular because the centripetal force that keeps objects in circular motion is constant (it is gravity!)
Gravity exerts a force on objects; forces change the motion of objects.

inertia
Gravity is the force which keeps them there.

The force that opposes motion when moving objects over a surface is called friction
