Kili, Hannah and Misha

From Zelda Wiki.org

Red-haired Kili, blue-haired Hannah and green-haired Misha are three girls that wait outside of the STAR Game tent in Twilight Princess. If Link wins the star minigame, he will gain them as fans; they'll follow him around whenever he gets close. If he comes up and surprises them, the trio will cheer, pop out three Recovery Hearts, then run away into the throng of Castle Town. Their individual hair color is most likely a reference to the three goddesses, Din, Nayru and Farore, and their respective colors.
