Ugh, the allignments were terrible. Thief Lawful Evil!? What were you thinking? Thief LAWFUL? And he's far too neutral to be Evil. A perfect example of a chaotic neutral character. Red Mage being chaotic neutral makes no sense, as he obsesses over rules. He is Lawful Neutral. 
 Princess Sara isn't really evil, despite the name. She just got so tired of being kidnapped. She's most likely Neutral good. Black Belt is pretty similiar to Fighter in his outlook, so I'd say he's Lawful Good.
