Air in the upper atmosphere speeds up.
Wind at the surface is slower than the "winds aloft" The biggest effect is within a few inches of the ground.

Yes. Double the weight and double the friction.

more rough surface more friction object have
The wind at the surface of the ground where the molecules are having friction is moving slower than the wind above the surface.
the rougher the surface is, the more friction there will be

friction
rubber shoes
No, it doesn't, the only important thing is the force perpendicular to the surface (weight) and friction coefficient.
Yes. Double the weight and double the friction.
the smoother a surface is, the less friction it produces.
The rougher a surface is, the higher the coefficient of static and kinetic friction will be.
