The force of friction does, but the coefficient of friction does not.
As the coefficient of friction is not function of the area or not related to the area of the contact surface so the coefficient of friction remains constant on the increase of the contact area. The coefficient of friction depends upon the material of the friction surfaces only.

A higher coefficient of friction indicates that two surfaces in contact have a greater resistence. A lower coefficient of friction indicates that the two surfaces in contact have less resistence. Soccer cleats on grass have a greater coefficient of friction than skates on ice.

Unitless, surfaces
The strength of the force of friction depends on the types of surfaces involved and on how hard the surfaces push together.
The friction is a number that represents the resistance to sliding between two surfaces in contact with one another. It is measured in Newtons (N).
The ratio of resistance force to effort force is a mechanical advantage.
Frictional force depends on the contact force and on the coefficient of friction. The coefficient of friction depends on the types of materials in contact; the contact force may depend on mass, if it is caused by gravity.
No. The coefficient depends only on the two surfaces which are in contact.
No, coefficient of friction is dependent on the materials in contact, not their mass. However the FORCE of friction will increase as the mass increases in this case.
