There are few characters missing. The one I was able to recognize are:

Nami: on the wave
Tracer: inside the wave
Varus: Shooting at Hanzo
Neeko: First in line to Mei shop
Katharina/Miss Fortune: Behind Neeko. Can't tell from hair color alone but I bet on Katharina
Swinging Dredlock hair person from Overwatch: The music guy is last in the line, next to D.va wrist
Black Widow: I think she is only woman character with blue skin color and purple hair from either Lol or Overwatch, Possible Evelynn.

Can't recognize the purple one and white one after Possible Black widow/Evelynn.

That fennec looks super-cozy.
