Chaos, Sleeping, Immobile cancel each other. I tested it using Shisui and Kushimaru. I chaosed a ninja with Shisui and immobile with Kushimaru on the same round, and the next round, its back to normal. If a ninja can suffer chaos and immobile at the same time, then he will still be chaosed on the next round coz Shisui's chaos lasts for 2 rounds. So yeah, they cancel each other.
