It's not even just the characters' reactions, it's also the cinematography they used, where they had Weiss and Blake on screen, with it looking like Caroline was looking toward Blake. This would infer that Weiss and Blake are the two major subjects that Caroline is speaking about.

We know that Weiss definitely was one of the major subjects that Caroline was talking about, since she specifically said "Miss Schnee" and was talking about being happy to send her home. When she mentions Weiss' friends being "of questionable character", she looks toward the other character in the shot - Blake.

From the way this scene is shot and the characters' reactions, my impression is that Yang and Weiss were basically getting offended for Blake, while Blake was upset with how Caroline looked specifically at her when saying that.

That's not to say that Caroline was only talking about Blake. She was putting emphasis toward Blake, but considering she said "friends", plural, she may have been talking about Weiss' friends in general, just with more emphasis on Blake than the others.
