The second one loves to make bows and other mane and tail accessories, she sells them at a booth she set up
 
The third one’s cutie mark is a strawberry and three blueberries, I didn’t come up with a personality or anything for her.
 
The forth one has a jester hat cutie mark, he can be a bit of a clown and likes to pull harmless pranks.
 
The fifth one’s cutie mark is paper and a writing quill, he likes to write poetry and love stories.
 
The last one is in an edgy emo band he and his friends started, he is a sweetie pie though, he dyes his hair red to match to aesthetic of the band. He is the lead singer. His friends/band members are all pretty cheerful, they started the band during their edgy teenage years but kept the theme as years went on. I’ll probably design his friends at some point
