Friction
Friction between two objects produces heat.
Friction between two objects produces resistance to relative motion, resulting in heat generation and wear on the surfaces in contact.
Mass certainly affects the gravitational attraction between objects; air resistance doesn't.
False. Mass and distance are the only factors that affect the gravitational attraction between objects. Air resistance is a separate force that opposes the motion of an object in a fluid medium.
No. Objects have to be in contact for there to be friction between them.

This is referred to as conduction, where heat is transferred through direct contact between objects. It occurs when vibrating molecules in a warmer object transfer energy to neighboring molecules in a cooler object. Temperature difference between the objects drives this heat transfer process.
The force that resists motion between objects in contact is called friction. It acts opposite to the direction of motion and its strength depends on the surfaces in contact and the force pressing them together.
gravitational forces are experience between to objects without any contact between them
I am not sure how the two objects of equal resistance are supposed to be connected. But for a current to flow, for example across a resistor, there must be a voltage difference between the terminals of this resistor.
Static and Kinetic friction, static is the friction between two objects when they are not moving (relative to each other) an example of this is and object staying still on a sloped surface. obviously, kinetic friction is the friction between two objects that are moving and making contact, for example wind resistance.
