Bonjour, hello,
You can't say "Suivons-moi". This form doesn't exist and is grammatically incorrect.
You can say "suis-moi" to somebody you know well (a friend,etc.) Informal form. (= TU me suis.)
You can say "suivez-moi" to a group of persons OR to a single person you don't know well. Formal form.(= VOUS me suivez.)
I hope I could have helped you.
Sincerely.
