No. Only four princesses have been named in the show: Celestia, Luna, Cadance, and Twilight.
Princess Papillon appears to have been an alternate version of Queen Crysalis created by the show's fans.
There is no known backstory for Queen Chrysalis as of yet, and it has not been confirmed if she was or wasn't Princess Papillon. Princess Papillion appears to have been a fan-made version of Chrysalis and so is not a cannon character. It is unlikely that Chrysalis has any connection with the Rainbow Kingdom.
