If you are logged into 2 laptops with a Google account, can the other person see what you are doing?

I sold my laptop 3 weeks ago, but I just noticed that I forgot to log out of my Google account there. So over Chrome, there my bookmarks etc. Are saved. Question: Can the other person see my history or see which pages I was on, etc? Reading emails should be clear, I'm only interested in whether someone can see my history, see which pages I have visited, etc., is there any information?

At least he can see the browsing history

Can I see somewhere on which devices I'm currently logged in with the account or when the device was last active?
