The HTTP Protocol is stateless by nature so in general you shouldn't be able to tell. However, you have have two separate sessions open you can track traffic by inspecting the HTTP headers for session cookie values, but that's about as good as you're going to get.

Under normal circumstances - no. If you aren't talking about google.com, and instead are talking about a webpage that you develop - then you can have a javascript variable (not a cookie) that's set and sent along with page navigation.

As long as that variable is unique (or random) - you can distinguish the instances. Cookies are shared between single browser multiple windows/tabs unless using "Privacy mode"

More information on what you're trying to accomplish would help better answer this question.
