I'm thirteen (nearly fourteen) years-old, a mezzo-soprano (range of F3-C6), girl.
I'm just working on building up a few songs to build up a selection I could choose from in preparation for any upcoming auditions for next audition season in the fall.
Contemporary AND classical showtunes pieces would be helpful!
Some pieces I already have the music for or know:

• "I Know Things Now" Into the Woods
• "Superboy and the Invisible Girl" next to normal
• "On My Own" Les Misérables (I don't use this at auditions for fear of it being too common)
• "Watch What Happens" Newsies
• "No One is Alone" Into the Woods
• "Happily Ever After" Once Upon a Mattress
• "Maybe They're Magic" Into the Woods
• "Fly, Fly Away" Catch Me if You Can
• "Pretty Funny" Dogfight
• "Someone Like You" Jekyll and Hyde
• "Somewhere That's Green" Little Shop of Horrors
• "In My Own Little Corner" Cinderella
• "Let Me Be Your Star" SMASH
• "You Don't Know" next to normal
• "Dyin' Ain't So Bad" Bonnie and Clyde
• "Wishing You Were Somehow Here Again" The Phantom of the Opera (all of Phantom except I don't want to use it at an audition cause common)
• "Defying Gravity" Wicked (again not used at auditions really cause common possibly)

Those are mainly the ones I have music for already. What are other (classic Broadway preferably) songs I can add to a binder for auditions?
Thank you for any suggestions!
If you can, keep in mind age with suggestions... THANK YOU THOUGH TO EVERYONE WHO PROVIDES AN ANSWER!

He most definitely can!! Acting requires a large variety of people, from different colors, shapes, sizes, backgrounds, you name it... Even diseases. I don't think HIV affects your ability to listen to people like directors and cooperation. I also don't think it affects your ability to connect with a role, so he should go for it! HIV should not stop him from his dreams! (Unless his dream WAS to be a pornstar or hooker because that puts others at risk) but you get my point

If you are practicing, try to make a personality with a list of characteristics that you both desire. No more than five. Try to act like that.
