Should I immediately pay off Student Loans?

My fiancée and I are getting married soon. She recently graduated with a bachelors and I graduate this December and am continuing my education by pursuing a graduate degree. I have no student loans and a full academic ride for my graduate degree, however she has 20.5k in student loans (about 7 loans ranging from 2%-5% from undergraduate.

We have $27,000 in the bank and $4000 in emergency funds. Should I go ahead and immediately pay off the student loans then put what is leftover in an HYSA?

Would love to hear personal philosophies, anecdotes and advice.
