These questions, you would figure it out once you watch the anime... but since RM is like 10th on your list, I'll answer it.

1. A doll make a contract by having a person kiss a rose ring they are wearing. Once this person kissed the ring, the ring will appear on one of the medium's ring fingers. In order for a doll to terminate a contract, she simply would return this kiss on the ring when it is on the medium's finger. This would break the contract then.

2. As of the last episode...

Spoiler for Finale:

Laplace's Demon has it along with Hina's. I won't say too much why he has it or why it isn't with Suigintou, you'll have to speculate yourself.
