First, we know that each semblance has a sound associated with it. Here https://www.youtube.com/watch?v=PzPZ6joXq5Y&feature=youtu.be&t=787 we hear a fuzzy noise in the background. Roman had just been annoyed at Cinder, the noise plays, he decides to relent.

And theeeeeen we hear it again here when Ruby bumps into Cinder's group https://www.youtube.com/watch?v=bdiV-w3yXos&feature=youtu.be&t=732

Ruby looked like she was about to be suspicious while the noise played, then her expression changes and she has no suspicion. For 1-There's something simple called Intimidation. Roman knows she can easily make his head explode into flames casually, which is why he relents.

For 2-That was simply Ruby thinking "haven't I seen her before somewhere...nope, doesn't ring a bell", in part due to not getting a good look on her in ep1, and in part because she's dumb.
