Can you help me name these characters?

I'm writing a story about these teens going on this adventure type thing but i can't think of any names to fit these characters that i accualy want to use. I had Layla for the main character but i'm not liking it anymore. And i had Mason for the boyfriend but i don't like that one either. It's not a fantasy, so no mythical creature names. Please help! :D

Main Character – She has big brown eyes, curly black hair, tall, long legs, light-colored. She's your average teenage girl. She has two best friends who are always by her side and a boyfriend who cares alot about her. She has everything going for her. She has a little sister who looks up to her. Her mom died when she was five. She's very adventurous, always getting into trouble. [16 years old]

Best friend #1 – She has pretty blue eyes, wavy light brown hair, also tall, pale skin. She's really preppy, always wearing skirts and flip flops and painting her nails. She's boy-crazy. She can never stick with a boyfriend. She doesn't like getting into mischief with main character but always ends up in her plans one way or another. She's really smart. [16 years old]

Best friend #2 – She has brown eyes, straight dark brown hair, very short, athletic, tanned skin. She's the tomboy of the group. She likes to listen to music. Doesn't really care what anyone thinks. She's always dying her hair color or doing some crazy hairstyle to it (like a mohawk, ect). She's always part of main character's trouble. She loves making her friends laugh and having a good time. She doesn't do well in school but she's smart. [16 years old]

Boyfriend – He has bright green eyes, brown shaggy hair, tall, popular, light colored skin. He's the boy that a lot of girls want to date but he only has eyes for main character. He's really in love with her. He's never involved in main character's mischief. He thinks she's gonna get herself hurt. He's a little protective and sometimes too protective but he's just being a good boyfriend. He works as a mechanic in main character's dad's car shop. He wants to buy her an engagement ring to show that he really loves her. [16 years old]

Main Character's dad – He's the cool type of dad. He likes to do alot of things with his daughters and their friends (like camping, ect). He's good friends with main character's boyfriend and he gives him permission to buy her a ring. He tries his hardest to raise his kids well on his own without his wife. He misses her ALOT but doesn't like to show it.

Main Character's sister – She's not really a big part of the story but she's there in some big moments and I need a name for her. She's cute. she's got strawberry blonde ringlet curls and dark blue eyes. She looks up to her big sister and wants to be like her when she grows up.
