Cortana can handle the first and the last one, and for certain queries she can "continue the conversation". For example, the following is possible:
Q: Show me Italian restaurants nearby. (list of 10)
Q: Which take reservations? (filtered list)
Q: Which ones have at least three stars? (filtered again)
Q: (with one result left) Is it open tomorrow?
Q: Call them.
Q: How tall is the Empire State Building?
Q: When was it built?
Q: Show me Italian restaurants nearby.
