If unbalanced forces act on an object, the motion of that object will change. Remember, force equals mass times acceleration.
Correct. true
The net force is the vector sum of all the forces acting on a body.
Yes
It is false. Change of direction is acceleration, which can only be produced by unbalanced forces.
No, they do not. Unblanced forces do.
Correct. true
An unbalanced force means that the vector sum of all forces acting on an object is NOT zero. Such an unbalanced force will result in an acceleration.
If a system is under balanced system of forces its true that it would not have any translation motion but the body can still rotate since torque can still be unbalanced even if the net force add up to zero.

Yes
It is false. Change of direction is acceleration, which can only be produced by unbalanced forces.
No it is not. Newton's first law states that an object at rest stays at rest (or in a constant straight line motion) unless acted upon by an outside unbalaced force. So the object would move if an unbalaced force acted on it.
there are no forces involved
The forces must be balanced; the forces must be equal in size and opposite in direction. (Net force must equal zero).
No, they do not. Unblanced forces do.
yes every unbalanced force can change or "try to change (can be or cannot be)" the state of rest or motion
