Answer

Yes the friction force can point in the direction of the object's motion.

Work Step by Step

Yes the friction force can point in the direction of the object's motion. For example, let's put a box on a cart and then start pulling the cart across the floor. The force of friction on the box provides the force to push the box in the direction of the cart. In this case, the force of friction on the box points in the same direction as the box's motion.
