The chick in the mask is Pantha. She was killed later by Superboy-Prime. She ends up as a romantic interest for Red Star, and is, incidentally, both a nineties anti-hero and a catgirl. She'd before her time.
The other girl is Mirage. She thinks she's from an alternate future where she and Dick were together, and shapeshifted into Starfire to infiltrate the Titans group of today. And in so doing, seduced Dick. She is only the first superchica to rape Dick, and not even slightly the last.
