If he is showing that he is curious to get to know you and learn more about you, this might mean that he is interested in you more than just a friend. This isn't just about him asking questions, but more so about whether or not he is listening to the things you share with him and showing that he cares about your needs.
You could do two things the easy one is you both ask him. Or theres some weird thing were if you are laughing you sometimes look at who you have a crush on/ like.
