My friend, you are a beautiful girl.
You are my heart and my soul.
First of all it's vous! not voes! It means "you are my love, my life, my everything.
It means you (plural) are my doctor.
vous êtes mon seul amour / mon amour unique: you are my only love
You say "my beautiful sister" in French as "ma belle soeur."
Me too, my beautiful girl.
"You are the one who makes my heart dance"
Etes-vous rentrer à la maison mon amour
"I think exactly the same, you are my world."
I think that you guys are my "cheri" I dont think cheri is a common word so... And it should be "Je pense que vous etes mes cheris"
Translation: You are sweet, my love. And my beautiful, I would like to take better care of you and I know that I am going to help you like I can.
Break a leg is "merde" or "je vous/te dis merde". Vous for someone with whom one is less familiar, te for a friend. The gorgeous part is a question of gender "mon beau" for a man, "ma belle" for a woman."Je vous/te dis merde, ma belle/mon beau" or, simply, "Merde, ma belle/mon beau." (Break a leg, my pretty.)
