There's not.

Pyrrha's is polarity and has nothing to do with her own name.

Weiss has glyphs because she's a Schnee but that would apply even if the family had a different name.

Blake's is Shadow and a flimsy tie in at best due to her name being black.

Yang's is unnamed at this time.

Sun has Via Sun but I'm pretty sure he named it himself.

Flynt's Killer Quartet is definitely not connected to his name.
