Power Plant Characters

So these are the 6 main characters of the power plant horror series that I think I'm gonna do something with. None of them have names except for Lilly, the cream one on the far left. As for the rest, I'm either going to ask people to name them, or eventually decide on their names when I feel like it. In case anyone has good ideas for names, I'll describe their personalities here. They should have normal human names (ex: Henry, Cindy, Julia, etc.).
From left to right:

Lilly - Easygoing, intelligent, and polite. She studies a lot of supernatural phenomena in her free time, but is also highly skeptical. She won't believe something unless she has absolutely no evidence ruling against it being true, and is on the hunt for something truly paranormal. She isn't very social, and she spends most of her time surfing the internet for new cases of paranormal occurrences and debunking them, or studying up on different mythological beasts. She tends to keep to herself, and hides her deepest secrets from even her closest of friends.

Gray cat - Smart, calm, and collected. He's a science enthusiast and doesn't believe most of the things he's told about regarding paranormal occurrences. He does know a lot about science, especially nuclear power. Like Lilly, he's not very social, and prefers staying at home and reading or researching to hanging out with friends. Although he may not express it, he cares deeply for all of his friends, and loses his head if anything happens to them.

Tan and pink cat - Optimistic, calm, and friendly. She suggested that the group of friends search the power plant as their school project, because she's very interested in the subject of nuclear radiation and power plant meltdowns. She's quite brave and puts her friends before herself, and will do whatever it takes to save them, even at the cost of her own life. She hangs out with them as frequently as possible, and introduced most of them to one another.

Yellow cat - Cheerful, friendly, and a bit crazy. She's happy-go-lucky almost all of the time, but doesn't react well in dangerous situations. She's very good at making friends, and she was at least acquainted with all of the other characters before they became actual friends. She's very social and wants to hang out other cats all day, every day. In dangerous and scary situations, she tends to completely freak out, and it's very difficult to calm her down.

Brown cat - Pleasant, laid-back, and fun. He's best friends with the last cat, and plays sports with him in most of his free time. Though he loves active things, he also likes reading, and spends a lot of time on the internet. He'll be very lazy or extremely active, depending on his mood. His main areas of interest are in math and soccer, but he was also interested in nuclear sciences enough to be on board with the project.

Orange cat - Hyper, cheerful, and mildly obnoxious. He's a jock and his main interests involve sports. He's not the smartest cat around, but his best friend makes sure that his grades in other areas don't fall too low, and he also has a few minor interests in some areas of science. He can be a bit oblivious and likes to make a lot of remarks that may not come at the right time. Even so, he has a good heart and just makes mistakes.

So yeah, if you want to suggest names, feel free to do so, but I already have some options if I don't think any fit just right. Also most of them are going to die. C':
