* Stephanie Zinone (played by Michelle Pfeiffer)
* Paulette Rebchuck (played by Maureen Teefy)
* Frenchy (played by Didi Conn, reprising her role from the first film)
* Rizzo (played by Lorna Luft, reprising her role from the first film)
It's worth noting that while Rizzo and Frenchy were original Pink Ladies in the first Grease, they were more like honorary members in Grease 2. They weren't part of the main group but were associated with them.
