I saw on RiftCat that they also support the Ocolus Go.
I use RiftCat to use my mobile phone as VR glasses.

Like as a normal monitor? you mean also for desktop? (possible)
It depends on the software, I don't know Oculus!
And what do you mean by normal games? Do you mean "normal" VR games, current VR games on Steam?
Nope
That's more for VR chat, watching movies via VR or watching events!
I think there is an option that your hand is tracked and you can interact with it.
But you have no controllers and no tracking boxes for the controllers.
