If Benjen is alive and well where do you think he is hiding right now, will the other stark members see him again and do you think he knows about R+L=J?

I think he knows b/c I think he helped Lyanna at Harrenhal and after, and that’s why he took the black. 

He’s hiding somewhere in the North, probably at or near the Land of Always Winter. 

And my guess is that he’ll encounter Jon when Jon goes North of the Wall.
