In the Avatar episode "Nightmares and Daydreams" (season 3), what are the anime toons that Aang dreams he is?

It is from season 3 episode 9, right before the "Day of Black Sun". He dreams that he is facing the Firelord several times. I know that they are "loosely based" off other anime toons (thank you Avatar Extras) but which ones? I think the first one is Goku from DragonBall, but what about the other two?
