Right foot is referred to the one right beside the stick's holding hand. It's flat part should always stay on the floor.
Right knee should not bend at all or you will have a less stability which is not advised. If the table's height does not suit yours
don't play on it. Watch others play which is a very profitable way to learn. Have your body(except your right hand) a thumb's length aside from the shot line but parallel to it while swinging the stick
. if the stick drops vertically to the floor it should not touch any part of your body. Do not let your right knee bend inward or out. your toes should stay in same direction as you stand in front of a mirror.
