No, the direction of friction is always against the motion. But in some cases it helps in motion by providing the necessary ration force to start the motion though its direction is aginst the motion.

 Consider, for example, a car accelerating forward. The tires push against the road in the backwards direction. Friction pushes in the forward direction and the car moves forward. Friction and motion are in the same direction. When a runner accelerates forward, the shoe pushes backwards, friction pushes forward and the runner moves forward. Friction and motion are going the same direction.

Not always, friction can go the same direction of motion in this example:
 
two cube (1st in the bottom and 2nd in the top) stacked on top of each other. we push the cube in the bottom so both cube goes in the +x direction. the friction for the cube at the bottom is in the -x direction but the friction on the second cube should go to the x+ direction to prevent it from falling behind.

no not always because for eg 
two cube (1st in the bottom and 2nd in the top) stacked on top of each other. we push the cube in the bottom so both cube goes in the +x direction. the friction for the cube at the bottom is in the -x direction but the friction on the second cube should go to the x+ direction to prevent it from falling behind.
