I'm not a very pro, but I talked with a lot of breeders and people who are having years of experience with rat snakes. Yes, beauties, like many other rat snakes can be kept together, but you must watch for a few things. One, it's better to not co-hab two males as they can fight for the territory, two, not every snake has the "Friendly enough" personality for the companions, so if you'll see that one of the snakes is aggressive/dominant for the others you should certainly replace that snake to the separate onclosure. And of course while feeding it's best to feed in separate boxes/places. I for example am keeping my Russian Rats perfectly fine together, but while feeding the one with stronger feeding response is feed in their enclosure, while the other on my hands, and I'm always waiting for them to calm down a little before putting them together again. If they are similiar size then they are really fast recognizing that it's not a prey, but their cagemate.
Well, that's about my experiences and point of view, hope you didn't feel offended by it
And I love your corn snakes! The other are cool too ofc
