If you have an above 50% winrate on all of those champs and play them only, you should be able to rank up if you can maintain it. 60% will definitely get you gaining 20+ LP a game.
Assuming you play them well enough yes.
No. Playing a champion that you yourself are comfortable with and like will be a lot better than just trying to blindly play champions who have an above 50% overall winrate.
No i mean that i personally have an over 50% winrate with over alot of games not just in general
