You can keep doing quest 2-5 or any other by going into Quest and scrolling to the bottom where it says Area List. Just choose which chapter you want after that.

The only way you can check what cards a person has is to initiate a Trade with that person. You'll be able to see their cards as long as they didn't lock them. If they're locked, you won't be able to see them.
