Four Kings are unusual in the sense that they are one of (if not the only) boss fight that it is actually safer to stand right in front of them and take the hit, rather than trying to dodge it. Here's some tips that will significantly reduce the damage they will do to you:

1. Get right up in there face as close as possible. If you are standing right in front of them, they hit you with the hilt of their sword instead of the blade, causing you to take roughly 1/5 of the actual damage. Try staying in front of them, because some of their moves can still get you with the blade if you are behind them.

2. Go back to the Undead Asylum and get Crest Shield. The mass majority of damage the Four Kings do is magic-based, you can block 80% of the damage from their homing projectile attack by blocking it with shield. Also, if you have Magic Barrier, use that too.

3. If all else fails, Havel it out. Unless you are on NG+7 or something, you can mitigate about 80%-90% of all the damage they do simply by meleeing them while in highly resistant armor.
