There are hundreds, hon, but I would think that your voice teacher would best know your range, what type of soprano singing best suits you, and can guide you in selecting songs for auditions. You and your teacher should be a team. Have you asked for his/her help? If you are training for classical singing, I would imagine that you should be looking at more "legit" musicals than rock musicals for your auditions.
