I (17F) am more attracted to his friend (both 17M). How do I move forward?

Hi I’m new to posting but I’m not quite sure how to navigate this new situation.

Tonight I was hanging out with a friend (F) of mine and we ended up running into this guy I know, this led to us hanging out with his friend group for at least half an hour before we had to leave. (Everyone is 17) Here’s the thing, the only reason we begun hanging out was because the guy I know was setting me up with his friend who I previously checked out not knowing it would go anywhere. If I’m being honest I just enjoy checking people out I can’t help it. My dilemma is I am really attracted to a different guy in the group who appears to be single based off of his instagram but I have no way of truly knowing at the moment. If you have watched off-campus this guy looks like dean.

When I got home the guy I got set up with was texting me and I was trying to keep the conversation very much like “oh let’s all hangout again soon” but he’s very much in to perusing me but I can’t say I’m truly interested in him when I keep thinking about his friend.

I don’t know what to do, and I don’t want to hurt everyone I just want to peruse the person I am attracted to.
