If I have a field has to be entered twice, can I hide the other one?

I have a form where someone has to enter their name multiple times. I added a condition where the name auto-populates, but can I have the other question hide from the person, but still show up on the PDF form answered?

Yes. You can hide the fields in the live form and still have them appear or available in the  Submission PDF document.
