The FORCE of Friction is INDEPENDENT of Surface Area. Only the 'Coefficient of Friction', and the Force between the two Surfaces. Sliding Friction is greater than Rolling Friction ONLY if the Coefficient of Friction is GREATER for the Sliding Surfaces.
If the two surfaces are moving relative to each other, then the friction between them is Kinetic Friction. Prior to the surfaces moving there was Static Friction between them.
The friction felt between two flat surfaces can either be sliding friction or static friction.
Sliding Friction If you push hard enough on the cardboard box filled with books, it will start sliding. If you stop pushing after the box starts sliding, it will slow down and stop. The force that acted on the box to slow it down was sliding friction. Sliding friction is the force that opposes the motion of two sliding surfaces in contact. Sliding friction exists between all sliding surfaces that are touching, such as the surfaces of the moving parts in a car's engine.

Yes. Without sliding friction or rolling friction, we would not be able to walk. It is the relationship between gravity, friction, and mass.
Friction is a force between to surfaces that resists motion. Static friction is the resistance to motion when two surfaces are not moving relative to each other. Sliding friction is the resistance to motion when two surface are sliding, one over the other. Sliding friction is less than static friction for the same two surfaces. For rolling friction an object is rolling, like a tire on a road. It's what provides traction between the two and makes the car "go." For a tire on a road, rolling friction is less than sliding friction.

Friction refers to the resistance that one surface or object encounters when moving over another. The two common forms of friction between two sliding surfaces are static friction and rolling friction.
The friction felt between two flat surfaces can either be sliding friction or static friction.
Kinetic friction is the friction that arises between surfaces in relative motion. Sliding friction is the friction that occurs when an object slides over a surface.
