Name my characters!

I’m writing a story which is sort of inspired/similar to the movie what’s eating [name_m]Gilbert[/name_m] grape but i cannot think of any names for my characters. i have descriptions below and i would really appreciate if you could suggest names for each of them!

younger sister (11-14) (protagonist), sheltered upbringing, autistic?, maybe, maybe not,

older brother (17-21) (sort of also the protagonist, maybe even more protagonist?) protective, drug abuse

brother (25-28), aloof, “travelling”, ran away, was the mother’s golden boy

brother (21-23), works as mechanic, breadwinner, aloof as well, loner

mother (dies early in book), protective, doesn’t want daughter who is her favourite to end up like the old favourite child, doesn’t let her daughter see the outside world
