No.
more rough surface more friction object have
Yes greater the surface area coming into contact friction would increase
As the coefficient of friction is not function of the area or not related to the area of the contact surface so the coefficient of friction remains constant on the increase of the contact area. The coefficient of friction depends upon the material of the friction surfaces only.
Yes
They have a large surface area so there is enough area for heat radiation.

Large particles have less total surface area, so caused less friction then the smaller particles do...!!

it is because the land is flat it has large surface area which experiences a large force of friction due to air and hence slows down

Yes
That would be the "pressure" on the surface.
Fluid friction will vary with speed and the area of contact when referring to air friction or drag. When referring to surface friction then only the area of contact will vary.
there is more surface area contact with kinetic friction as opposed to sliding friction
They have a large surface area so there is enough area for heat radiation.
