If I am understanding right, what you are trying to do is not possible.

When you put your alts on follow they will automatically face you. If you turn your main, and do not pass that turn command, the alts will still have you on follow but will face you. If you pass the turn commands, they will turn with your main, but drop follow. The moment you put them back on follow, they will turn to face your main. (just how the follow mechanics work).

If your main is melee and alts are ranged, I would just park them at the 25-30 range mark and rush in with your main. That should eliminate the need to turn them.
