[DC]Could somebody with multiple personalities use different Latern rings?

Assuming each individual personality corresponds to one of the spectrums. Or would the rings not react to fractured minds? If two personalities fit the same spectrum could they power up the ring beyond its usual capacity? 

Let's say Sensui from Yu Yu Hakusho. His main personality could likely tap the green spectrum while his rage-filled, bloodthirsty personality would fulfill the requirements for the red spectrum.

Absolutely. Hell, there are people with a single personality that have wielded two rings at the same time (Hal wore a Green and Blue Ring for a bit and later a Orange and Yellow at the same time, and Guy Gardner wore a Green and a Red Ring for a decent amount of time, and Red and Violet in an emergency) Kyle wore all seven at once on his path to be the White Lantern.

I have a feeling with your example that only the ring of the personality in control would be effective though.
