If you could rename these characters from Glee, what names would you use?

Rachel Berry (Lea Michele), Cory Monteith (Finn Hudson), Chris Colfer (Kurt Hummel), Quinn Fabray (Dianna Agron), Sam Evans (Chord Overstreet), Brittany S. Pierce (Heather Morris), and Noah "Puck" Puckerman (Mark Salling). THEY HAVE TO BE REAL NAMES NOT MEAN NICKNAMES. -_- :)
