The last character you posted I recognize (besides the cartoon I haven't seen) is Yelena Belova.  Maybe a quick summary of who these people even are?
		
		
	 
KRYPTON aptly explained 
Alan Quartermain, who is named after the pulp adventure character.
Slyde is a D rank Spider-Man villain from the 80s, a former 
N.A.S.A. scientist who got fired, and made surfaces that don't let anything stick to them. If you watched the 60s cartoon episode 'The Slippery Doctor Von Schlick' you'll probably notice the resemblance.
Phantom 2040 is 
Kit Walker of that time, made up for that 90s cartoon with the same name.
Richard Rory is a friend of 
Man-Thing, and he had a crush on 
Jennifer Walters, he also dated her. A DJ with a lot of down time.
Lou Monkton was a client of 
Jennifer Walters before her 
She-Hulk identity went public.
Mark Raxton/The Molten Man had cold molten metal attached to his skin, and was cured by 
Harry Osborn.
Martin Soap is from the anti-Punisher task force, and he's an ally of 
Frank.
Black Racer is not black in skin, she's a fast member of 
Madam Viper's organization; 
The Serpent Society.
