I think it is important for you to remember that she is just another person, just like you.
You have made friends before, I assume, you can find something to talk about quite naturally with people.
It is just important to not overthink this and feel pressured to talk.
You can literally talk about anything. If you don't know her that well than you talk to get to know her.
Tell her about yourself and what your everyday life is like, what you do and ask her the same.
I know it is natural to be nervous, but just remember that you are two normal people hanging out with each other, that is all.
Don't feel pressured to hug or kiss her, if you feel like it, do it. If you are just scared of doing something like that and feel nervous, but would still like to do it, then do it anyway. I don't see why you wouldn't hug her, I would hug literally anyone, but I know there are people who are uncomfortable with it.
Just be nice to her and be yourself, that really is all there is to it. No one smart will ask you for more than that.
If you like each other, then you will get along quite fine.
No need to worry about small details like that.
Good luck on your date!
I hope you have a good time
