Josh Castille Hamilton video

In Josh Castille’s translation of satisfied from Hamilton, when the song says “is that right” at 3:11. I haven’t been able to find the sign. 

Pointer finger curling on the chest? 

Then at 3:53 he signs pointer finger under a flat palm? I can’t find either. 

I’m a first year student so I don’t know if these are basic signs? I’d appreciate anyone that could help!

At 3:11 I think it's a question mark.
