How to store several inputs to a list and add a number picker for each in Xamarin Forms

I'm curious as to how you can store up to 3 input fields - each attached to a user-name typed into another input field (on the same page). Then after pressing a button and going to a new page: displaying a list of all the inputs made (except for the name) in a random order and attaching a picker to each - from which you can pick a number between 1-10.

If you don't know how to write the code - is it possible to link me to somewhere where I might learn how to do this? Thanks!
