Tips: 100TP break free always goes last, and requires you to still be able to cast spells. If you get muted/mouth covered, it'll fail, so always use it a step -before- this happens.
Chapter 1
Metal Faries:
This fight really is just 'use AoE, hope you dodge at least once to not be muted, use AoE and win' fight.
Water fairy:
There's a water vest you can get that reduces water damage you take by half, and there's also a thunder base usable item you can find by looking around. If you use the latter, you'll just stun her outright letting you KO without thinking, while the former lets you thug it out and just ensuring you escape her water attack before you're stuck drowning.
Dark Elf 1:
Don't wear the collars you found in the box in that room or earlier doing this or the next Dark Elf fight or you auto lose. You need to make good use of the AoE spell to keep the mobs off of you, but they'll respawn as well. Make sure you break free if she gets two rings on you, as then she'll do 4, and then slap a collar on you herself. Even if you break free by that point, the collar's a game over.
Dark Elf 2:
There's a fairy who wanted a carrot, you grabbed some in the cavern, so give them the carrot, and they give you the 'Elven Ring'. Doing this fight whenever the Dark Elf empowers her spell on the knight, you -must- use the 10 MP petragram icon spell to negate it, allowing you to attack them once more. Otherwise you'll be stuck in an endless loop.
