Frictional force is a contact force which opposes the relative motion. It is directly proportional to the normal reaction between the 2 surfaces.
It's a contact force.

Sliding friction
Static friction
sliding friction
Static friction produces a greater force than kinetic friction, given that all other conditions remain the same.

Sliding friction
Sliding friction requires more force to overcome its friction.

Coefficient of rolling friction will always be less than that of sliding friction. Hence more force is required to overcome sliding friction. Because the force = coefficient of friction x normal force (ie weight of the body)
