Access user information based on list

I’ve created a List with a ‘Person’ column to manage favourite people. So the operator will add a few favourite people to the list. It appears that the person column can only return a single attribute. Then I want to display the favourite people on the home page with other details like phone number, email address. So I guess I need to create a webpart that reads the list and then fetches the email address and phone number from user profile and finally displays the info. I’ve been reading that SharePoint also has a hidden list (_layouts/users/details.aspx) but this only gets populated once a user accesses the site, so this wont work. Hence I think User Profiles is the option here. Any ideas how I can achieve this? Thanks
