Direction of Friction for Rolling Motion

A ball is attached with a string on the side. When the string is pulled up, static friction accelerates the ball forward while the tension rotates the ball.
When a ball is placed on a incline with friction, is kinetic friction opposing the motion and giving the ball torque while gravity accelerates the ball down? Is there also static friction is this case?

Also, does the ball lose energy in either case due to friction?
