Vorhi: Blind Kung-fu master....take away the force and give him vague, physics-hating ki powers (and magic blindsense), and you've about got it. Not really much of a change in jobs or roles here.
Mr. Ash turned Amaranth: hard to even know where or how to begin that translation at all. Ash was a soulless killing machine that gained a conscience. Imma steal [member="Fabula Cavataio"] 's answer and say a golem who grew a soul as a fluke.
Olom Grihk: Some sort of stunted, angry, illithid-esque jerk who spends most of his time skulking in a cave for reasons. Evil mage type.
Olidiv Kenu: The winged viking portrayed by BRIAN BLESSED!!!! in the Flash Gordon movies, but with more swords.
Sugar: I'd keep the wingtip shoes and jazz music. They're just as out of place in your typical fantasy setting as they are here.
General Mayhem: Probably some sort of highly intelligent wasp-mutant. Terrifying and unpleasant, really.
