Yes. Weight, being a force perpendicular to the surface, affects the magnitude of the friction, but not the friction coefficient.
if the mass is more than the friction is high. and if the surface is rough then also the friction is more. thus we can say that both mass and surface type affects friction.
Water can make a flat surface more slippery, which will decrease the amount of friction
The larger the contact surface, the more friction. The more uneven the surface, the more friction. The material of the surface has also an effect on friction.

Yes, magnetism is a force. Any force applied to an object will either increase or decrease the friction between that object and an adjacent surface.
It would help if the question was less obscure. What do you mean by "work"? How the surface area affects chemical processes (for example the surface area of catalysts), or diffusion, or surface areas and friction?
There is friction that slows you down. There could also be water currents.

it affects the surface tension because of its temperture
Surface friction ALWAYS point parallel to the surface and opposite motion. There must be a normal force for there to be friction
All friction affects a moving object, the source of the friction and the object moving is irrelevant. Water on a soccer ball would effect the performance of the ball.
