I actually never planned on getting my first conure.... but he needed a home and my family said yes. Heck, the person who had him didn't know what he was, and me, being inexperienced, and with the lack of information at the time, it took me several months having to shift through poor information to determine what species I even had!
I was starting to fall for another species of conure as I was learning about them when I was offered to adopt another species like the one I already had... except he's not the same species... rather a similar species that is easily mistaken for the species I already have! That's Charlie. My first conure, Noel, wasn't exactly friendly, cuddly, playful... nothing a conure is described as. Charlie was everything I heard conures were supposed to be, so I said yes! I guess, in the end, he's not typical either... but he was the opposite of Noel in health, likes, dislikes, personality.... in everything except coloration!
Three years after Noel's passing, I saw Jayde here up for rehoming. I very tentatively inquired about her and was excited when I got the yes. We had to ship her, via airplane, to me and she was the funniest, quirkiest little thing! Unfortunately, she had a short life.

There was also Finn... someone I know who has birds, their uncle found him on Craigslist and when he didn't seem to be as cool or amazing as his nieces birds, Finn was neglected... so she took Finn away and more or less shoved him into my hands. Sadly, he was pretty sick and lived an even shorter life. (kidney failure)
And then there's Merlin. His human kind of grew up with birds when she was younger, she has a family, including large dogs, saw Merlin and bought him. She honestly did the best that she could for him, but she didn't know how to connect with him. We had spoken on and off about him before, about me possibly fostering him but when she finally made the decision to let him go, I was recommended. I made sure she was ready to let him go before taking him because it's such a huge decision. He's honestly a lot happier here than in his previous home as he doesn't have to worry about big dogs scaring him (I do have a big dog! But he's not allowed around the birds) or just being scared and nervous in general. He's quite the demanding little guy! And copies Charlie's scream. It's quite amusing hearing a mitred conure's scream coming from a green cheek! Between the two of them, it's quite fun listening to their vocalizations!!!!
From having more than one conure, or well, birds in general, I can say that they do in fact benefit from having other birds around, even if they don't get along. I saw this clearly with Noel and Charlie. They did not get along, but Noel did attempt to copy whatever Charlie was doing... even though Noel was older. I also think that Charlie helped Jayde in some way as well since she was very skittish and afraid when she came here. They had sort of a love/hate relationship. That is, they *could* get along, but they didn't *love* each other... and if I had one on each shoulder and one was preening my face, so was the other! But god forbid, if one of them passed that invisible barrier in the middle of my face that split who got to preen what side, the other bird would get upset! Not fun to have two birds beaking each other across your face... lol
I have also fostered a green cheek and while she was here, it really helped Merlin. Merlin is also a very skittish and shy bird. The other green cheek was not, so him being able to see another bird being okay with humans gave him more confidence to do the same. Due to the size difference between Charlie and Merlin (Charlie is easily about 4 1/2 times bigger!), I don't really allow them to interact. Charlie might not be able to do much damage, but I'd rather not take the chance with a bird who's head is basically the size of his beak!
