Alleria : elf, royalty, ranger, holy, magical, manipulator.
Gerald : human, knight, holy, swordsman, assistante.
Malik : human, warrior.
Bolin : dwarf, inventor, gunner, toolist.
Magnus : human, magician, illusionist.
Ignus : elemental, warrior.
Denas : royalty, assistante.
Ingvar : human, shapeshifter, anceteral, warrior.
Elora : elemental, magician, manipulator.
Oni : demon, unholy, warrior, swordsman.
Hacksaw : gnome, inventor, toolist.
Thor : godly, holy, elemental, warrior, manipulator.
Alleria: She doesn't come across as Holy to me. None of her abilities are tied into it and her personality and background aren't a match either. I wouldn't say magical or manipulator are suited to her either. I'm not even sure what you mean by manipulator.
Gerald: What do you mean by assistante? Is he French?
Malik: That's not much to categorise him by, especially when you're putting so much into other form. Tank? Brute?
Bolin: Toolist is an odd word for what I assume you want to mean 'uses tools'? In what regards are tools different from any other kind of weapon?
Magnus: Not much I'd add here, but I'd consider using a word like Sorcerer instead of Wizard. The former suggests a powerful being, the latter card tricks and pulling rabbits out of hats.
Ignus: Yeah
Denas: I see the King is undeserving of being classified with a species.
Ingvar: I assume you mean 'ancestral' but that doesn't really mean anything. I'd suggest you added 'summoner' or if you wanted it to be correct 'necromancer', since he is calling on the spirits of the dead to fight for him.
Elora: Human, not elemental.
Oni: I don't think you need warrior and swordsman.
Hacksaw: Can't really help without knowing what toolist means.
Thor: Eh, i'd make his species God as oppose to him just being 'godly' since the game clearly states he is a demi-god. He's not an elemental in the same way Ignus is, and again what is this 'manipulator'?

Everything that follows: I see you'd started to run out of unique categorisation now. Everything seems to be a Warrior, Toolist or Manipulator. Grawl gets to be a humanoid elemental, whilst Ignus (who looks more human in shape) does not. Cycrab? That's a horrible term, nobody would actively look for that, it needs to be a species and another form like 'Mollusc, Cyborg'. If Mirage is a ninja what does that make Kutsao?

I'm seeing the same thing here. Almost everything has magical and manipulator. There's no variety, everything is going to be classified so similarly that there's nothing to set them apart.
I think you need more clear cut definitions for each class, and everyone should have at least one from each field, even if they aren't very interesting. For example:
Species: Human / Humanoid / Elf / Dwarf / Non-Human / Elemental / etc.
Class: Warrior / Rogue / Thief / Mage / Bard / Inventor / etc.
Battle Type: Offensive / Defensive / Tank / Healer / Mixed / etc.
Combat Type: Close Combat / Mixed Combat / Ranged / Magical / etc.
Alignment: Fire / Water / Thunder / Dark / Light / Neutral / etc.
And then you can add things on to each of the subjects you choose, for example:
Gerald: Human;Linerian, Warrior, Offensive, Close Combat, Light;Holy
Alleria: Elf:Aredhelen, Rogue, Offensive, Ranged, Neutral
Bruxa: Human, Mage, Mixed, Magical, Darkness;Necromancy
Ashbite: Non-Human;Dragon, Warrior, Offensive, Ranged, Fire
Lynn: Elf;Twilight, Thief, Offensive, Close Combat; Darkness
Bravebark: Non-Human;Ent, Mage, Tank, Mixed Combat, Earth;Plant
You'd need more than I have here if you wanted to include things like weapons, technological level, etc. But this is just a start.

. I don't claim to be a pro in the classification district so I'm open to hear all oppinion, and I see that I forgot somethings (unintentionally 
). For "manipulator" it means that he manipulates his surroundings to use a skill, create assisting troops, etc.
