I have to echo what has already been said.
Charlie loves a cuddle and comes at every opportunity to be cuddled. Tommy likes to sit on you and be petted but not much for cuddles. Jade likes her own space but when she wants a cuddle she comes and tells you in no uncertain terms, then she likes to be hugged or held like a baby, usually you have had enough before she has but when you put her down she looks as if to say thanks and then goes on her way. Sol is also very independant and will come to be stroked and to have a chat with you, loved a cuddle when she was a baby but not bothered now, I guess she has grown up.
I don't think Charlie will ever grown up
Just give Little Egypt time, show her affection but don't force it on her if she does not appear to be enjoying the attention leave her alone, she will know where to go when she wants it.
She has had a very traumatic time, new home,new friends, big op etc... it will take time to settle in, but I am sure she will come round with time
