#1 is definitely Little House on the Prairie, they already had there Equity auditions for this.
The little flying thing on the left of #2 looks like Tinkerbell to me, does anyone else see it? It's got to be, I am guessing Peter Pan.
#3 Random guess: Lost in Yonkers
#4 Random guess: Titanic (but I doubt they would do such an expensive musical right now)
#5 Guess: Smokey Joe's Cafe (thanks to LavieBoheme below)
Edit: #5
