This might not be the answer that you want, but from my experience, getting a group that close to eachother would be extremely rare, even in college. I’m currently a sophomore as well, and I’ll tell you right now, even I don’t have a group as close as that. We all hang out with eachother occasionally, but we’re all also independent as well. That independent part is kinda what college is all about. I mean of course it would be nice if you could have a group of friends who all knows eachother and are all super close, but getting one of those groups together isn’t gonna be easy, especially when people in your group might have different interests or just want some space to themselves. The easiest way to get that super tight knit group imo would be to join a frat/sorority, but even then, there will be some talking behind eachother’s backs.
If you wanna develop stronger relationships, maybe it would be best to try and do it with one friend at a time rather than just hanging out with a group of people. Quality over quantity.
Other than that, I don’t really know what to tell you besides to just keep your head up and keep trying, cause eventually you’re bound to meet someone that you can relate with.
