I looked them up, and as Lalafell are a species original to final fantasy, I would rather not to use them. This rp will revolve a lot around world building, so common races with their own twist, mythology, or original species are preferred.

The limit on taming is relative to rank. At copper, you can have one creature at a time. At iron, you can have two. At Silver, three, and so on. You can tame new creatures even if you're at the limit, but you will have to release one of the current beasts.
In general, taming possibility depends on how similar the attributes are. As Xar'on has excellent strength, larger, more powerful creatures would be easiest for her to tame. Boars, hunting birds, bigger felines, and such-like. Smaller animals, which tend to be agile and dexterous would be much harder. Same with highly intelligent creatures.
