Motion is always relative to the observers frame of reference. For example, if two people were standing facing each other, and a dog walked between them, one person would observe the dog's motion as going to the right, and the other person would observe the dog's motion as going to the left.
Friction is a force that always opposes the motion of an object. It occurs when two surfaces are in contact and resists the relative motion between them.
Motion is relative because it is always defined relative to a reference point or frame of reference. An object's motion may appear different depending on the observer's perspective or frame of reference, making it a relative term. This is described by the concept of relative motion in physics.
True. Motion is always observed relative to a frame of reference, which provides a fixed point against which motion is measured. This allows us to quantify and describe the motion of an object accurately.
Frictional force always acts in the opposite direction to the relative motion between two surfaces in contact. If there is no relative motion, the frictional force resists the impending motion between the surfaces.
Motion is always relative to something. There's no such thing as really "stationary."Stationary only means that the motion of the observed object matches the observer's motion. Example: Reading the book that lies 'stationary' in your lap while you're in a car or on a passenger jet.
He is in motion relative to me, and he is at rest relative to his friends. There is no 'real' rest or 'real' motion. It's always measured relative to something else.

There is no singular motion because everything is made up of subatomic structures going many directions and so therefore any object's motion is always going to be relative motion in it's consideration.

Never, because it's always relative.

The resistance force that always opposes motion is friction. Friction is the force that acts between two surfaces in contact and it opposes the relative motion between the surfaces.
Friction opposes the relative motion of surfaces in contact. It acts in the direction opposite to the direction of motion or tendency of motion between two surfaces.
