My girls (yes, all female):
Uno (the bossy/spicy one). Super friendly, will let you hold her like a baby and pet her whenever you want. But pet her for a second too long and you're bound to get a warning nibble. She bosses all the other ones around.
Socks (adopted with Uno) - the shy/skittish/goofy one. Only comes to me and only me for pets, easily startled, will stare at everyone and just generally a strange cat. My son says she is on the spectrum. Doesn't meow, never bites, very gentle.
Luna (the princess/needy one) . The most vocal of our cats, loves attention and very affectionate.
Nori - the brave baby. All our other cats are around 2 years old, but Nori is only 6 months old and very tiny but will stand up to all the other cats. Very sweet. Loves pets, but hates getting picked up.
We got Uno and Socks when they were 12 weeks old. Luna and Nori about a couple of months ago. Introduction was very hard, but they seem to get along fine now (for the most part).
