The forces acting on it will be the force of gravity downward, normal reaction by our hand upward, there may be some forces like due to wind and the frictional force exerted by our hand in opposite direction.
you can see that all the forces on the bag are in opposite directions such that each and every force gets cancelled. so no net force acts on it.
By Newton's first law, we can conclude that the bag doesn't change its state of rest or motion.

(a) Force of gravity acting downwards i.e., the weight of the bag.
(b) The hand applying an equal and opposite force on the bag.
