6A. Explain why you don't know whether the ball is moving in the +x or -x direction, or not moving at all.
You can tell what direction the ball is moving. The +x axis is labeled in the direction of the unbalanced force. Therefore you know what direction the ball is moving in.
6B. Explain what would be happening to the motion of this ball if it were moving in the +x direction, with forces exerted on it by other objects as shown.
The stick is pushing the ball in the positive direction.
6C. Explain what would be happening to the motion of this ball if it were NOT moving yet, with forces exerted on it by other objects as shown.
It has to be moving because there is an unbalanced force shown.
6D. Explain what would be happening to the motion of this ball if it were moving in the -x direction with forces exerted on it by other objects as shown.
The stick would have to be pushing the ball in the opposite direction for it to move in the -x direction.
6E. Explain the relationship between the direction of the total force exerted on the object of interest and what is happening to the motion of the object of interest.
If there are balanced forces, then there is no movement, however the addition of an unbalanced force means that it is moving.
