How to ask my crush out?

[Puppy]

Ok there is various questions put together here and i honestly don't know how to come about them! So any help will be great!
Im 13 years old and i really really like this guy grade he's in none of my classes but i always see him at lunch his friends are friends with my friends too. He plays viola in the orchestra i go to too!
First i wanna know how to talk to him! Full details please!
Second i would love some tips on how to make him like me without friend- zoning him ?
Thrid there is another girl in my grade who really likes him too he knows that she likes him and he does not like her but she keeps stalking him on this social media site asking people loads of questions about him and I'm worried if i do end up going out with him people might think its me that was
Annonmosly asking loads of questions about him what would i do in that situation? Wouldn't everyone tease me then?
What if he doesn't like gingers? I am a ginger haired girl!
And btw please don't tell me i am too young i have already thought all of that threw and i am ready for boys
Thanks so much for your help
By the way im kinda shy so the easier the better! Lol
