Meat Boy is supposed to be a callback to nes games with stupid simple stories so he doesn't need to be a multi-dimensional and complex. With that said, in cut-scenes, he is shown to be risk-taking, nice but a hint of cynicism (kicking and euthanizing C.H.A.D, being disappointed by jill, ogmo, and the kid, tired chase through saving "bandage" from warp zones), determined, and somewhat of a quick thinker (utilizing somewhat non-violent ways to take out the bosses at the end of each word).
Hominid is a call back to metal slug, which again, usually don't have that much in terms of story. With that said, he's shown to be "childish" (which is really just to say, he is homicidal and giddy when victory) yet still co-operative, least when unprovoked, as he works with the fat kid fairly well.
Pico's personality in the original games is more or less dependent on the player's choice. Being described as "the people's character" by the man himself, fan works usually portray him as homicidal smug jerk who likes to smoke weed. In the fulp stuff however, that seems to be only the case when in dire situations, such as a school shooting or an uberkids attack. Most of the time (or at least the glimpses we get in first seconds of School and 2), he's shown to be reckless but mostly well-meaning, he has a quick mind as he's able to think of solutions to problems in a matter of seconds using unusual items, outspoken, confident yet vulnerable (and knows how to hide that vulnerability), and has a hint of a "goofball" side to him, being exceptional at dancing, and of course, being happy in the clouds while he's high (a contrast to the usual brooding in fanworks and even fnf (least in-game)). Again though, it really depends on who's making. There's a difference between Tom's Pico and the NG's Pico.

Hank is a killing machine on autopilot and that's really all he needs to be for the series. Though he has some dry-wit and rare cases of caring for his "tools" (Nexus and Madness 10)..
