An object is in equilibrium if all the forces on it in all directions add to zero. Since the ball is only acted on by gravity, there is no other force to cancel it out, so the ball is not in equilibrium.
In other words, if the ball were in equilibrium, it wouldn't be accelerating, but it is clearly accelerating towards the ground.

No because even though the balls speed may stop at a certain point gravity is still acting on the ball causing the ball to have a negative acceleration of 9.81m/s.

You could say so, though it is a very brief and transient equilibrium. The ball's upward momemtum is exactly balanced by gravitational pull for an instant.
