How to make conversation with this girl?

There’s this girl at my job that I’ve barely spoken to until yesterday. She’s sooo pretty. I basically asked her every question I can think of about herself but the questions I asked about herself she kinda asked them about me but didn’t give short answers. Like I asked her if she was dating anyone to be 100% and she said no which was good. But she knows I like her I don't know about her but her friends were coming up and giving the heart hands and making her laugh so maybe she does. Her English isn’t the best and it’s a loud area so I was stuck. What other questions could I ask?
