Frozen oysters could last up to four months.
Yes. Most shells - like oysters - have a very long history in time, much more so than humans (homo sapiens) who started out as a species no more than 100 to 200,00 years ago which in terms of the planet's history is very, very recent.

Oysters can be eaten raw as long as they are fresh. To cook them, you can boil them, bake them, or barbecue them! mmmmm... good stuff!

As long as your willing to eat them. This is a tough question to answer. If the oysters were on the verge of spoiling prior to cooking then that changes everything. It also depends on how they were cooked. Fried oysters will be fine refrigerated for a few days where as oyster stew will be good for just about a week. Seriously I wouldn't eat cooked oysters more than 3 or 4 days old.
