    g doesn't change. All of them = g.

    even though when the ball leaves your hand is still equal to g, wouldn't it be greater??

    You are thinking about velocity. That changes, but g does not. g is the change in velocity near the surface of earth. If you're still confused you should read your textbook. All of them gives a good description of g.
