Only a handful of these characters have offical comic counterparts.
The Wonder Twins were only recently introduced in YOUNG JUSTCE. Their history is more or less open to interpretation, since they only appeared for two issues in a minor capacity as two jerk alien meta-morphs who don't speak english and eat CD's.
Black Vulcan is simply Black Lightning, former secretary of education for Prez. Luthor, and blessed with the ability to create lighting (in his pants...)
Samurai and Apache Cheif were both in comics for a bit, but disappeared into comic limbo. There is little if not no information on them on the web in comic-dom.
Wendy, Marvin, Wonder Dog (oh how I hated them...), Gleek, El Dorado and Rima, were never introduced into comics. So they don't have counterparts.
