I was able to identify most of these Marvel heroes, but who is the woman with white hair behind The Punisher? She is circled with a light blue (red had too little contrast) freehand circle in the top right corner.
That would be Black Cat, Marvel's answer to Catwoman. She's a cat burglar who has had a flirtatious relationship with Spider-Man since the mid-1980s. You can read more about her at the Marvel Wikia
