Name for a character?

Hi, Im writing a short story essay for my English class and I'm looking for suggestions for first and last names for each character. Thank you!

main character:

8 years old

scrawny/wimpy

red hair

freckles

glasses

short

nerdy

other characters:

three to five bully names. (these don't have to have last names, maybe just names for the two main bullies who taunt the main character.

A name for the girl who the main character has a crush on, she's a little girl who wears her blonde hair in a side braid and wears dresses every day.

A name for the main character's teacher. She's in her fifties and is kind of shrill.

thanks so much!!
