She may never learn to love them, but she'll probably get used to them and tolerate them eventually. She'll need a lot of time and exposure to accept them though. Keep bringing them out and leaving them within her sight as often as you can. Eventually you'll be able to let them all out together, but there's no way of knowing how long that will take. Read her cues and let her guide the process. If she still puffs up, then she needs more time. If she's okay most of the time but occasionally still puffs up a little, then probably needs a little more time. When she starts just ignoring them, you can probably try letting them out together, somewhere with lots of places for the seramas to escape if need be (things to hide behind or under). And supervise those first outings carefully. They'll get used to each other, it will just take some time.
