Friction does depend on the types of surfaces involved and how hard the surfaces push together. Friction would be very minimal if the surfaces were smooth and not pushing together too hard.
Yes.
The amount of friction depends on the force pushing the surfaces together.

friction
Yes.
when 2 surfaces rube or slide together the more smooth the less friction
The amount of friction depends on the force pushing the surfaces together.
two rough surfaces
The coeffient of friction. The force holding the 2 surfaces together.
friction
Force pushing two surfaces together
Yes but make sure you are clear in your understanding between the coefficient of friction and the force of friction. The force of friction is the force that resists the motion of two surfaces moving against one another. The amount of friction is determined by the product of the coefficient of friction and the normal (perpendicular) force that is pressing the two surfaces together. The coefficient of friction is a unit-less constant, that indicates how two surfaces compare to two other surfaces that are being pressed together the same amount. If the normal force is the same on two pairs of surfaces the pair of surfaces with the lowest coefficient of friction will experience the lower force of friction.

Friction that is caused by the movement of two surfaces against each other is known as kinetic friction. This is different than static friction which is opposition to motion before the motion occurs.
