Database development for Gym App

I have an idea to create a gym app that groups users based on certain preferences so they can find people to train with.

I have asked 50 people to answer the questionnaire below.

I need a database developed to store this data and queries created to group clients based on the following criteria:
(1) the gym they attend.
