Help me

Ok so im a dude and ive bitten my nails my entire life and i decided recently that I wanted to stop and grow out my nails. So my first question would be, the pink part of nail is very wonky. And has a very stupid shape especially on my middle finger. And id like to know if theres anyway i can reshape the pink part so its more like on my pointer ? On my pointer its pretty uniform and smooth unlike all of my other fingers. Yeah don't judge the shape of my nails idk what I'm doing I was never taught how to take care of them. 😭
