That's the 'kinetic' kind..
Friction refers to the resistance that one surface or object encounters when moving over another. The kind of friction that sliding objects experience is sliding friction.
The normal force between the two objects and the coefficient of friction. Force of friction = normal force x coefficient of friction.
Yes, heavier objects do experience more friction. This is because since they are heavier, it means more gravity is pushing down on the object. Because there is more gravity on the object, it pushes on the ground harder than other objects. This increases the friction on the object. It would be like you rubbing your fingers together softly. Your finger slides easily, right? If you push down harder, it becomes harder for your fingers to slide. It is the same principle, but just on a larger scale.
Increases friction
No, friction is the force between to objects created by gravity.

limiting friction is force of friction when a body slides over the surface of another body
No. Objects have to be in contact for there to be friction between them.
The force of friction is a contact force. An example of a force at a distance would be gravity.
Sliding friction, (possibly) applied force, gravity, and normal force.
Friction force. [opposite force]
No, friction is the force between to objects created by gravity.
Increases friction
Since friction means a contact force, the nature of contact will influence friction force. Smoothness of objects affect the friction force. However, as contact pressure rises, the friction does not rise.
In the direction opposite to that of the sliding body.
