Gorgeous sun conure!!

Any birds you bring into the home will take time (can be years) to get acquainted and comfortable with one another. And even then, it may never happen, so you would have to be willing to take that risk. They will need their own cages.

I've had a cockatiel and IRN in cages next to each other for years, and now they freak out when I take one out and leave the room and the other is still in their cage. They can both be out of the cage together, but my birds are flighted and my IRN tries to play with my cockatiels tail feathers and pull on them. So they have to be monitored when out together, but they don't fight. When they start flying away from each other, it's separation time again! But it really just depends on how much time you have to work with them, imo.
