Depends on if they're on tabs the viewing user can access. If the Access for the tab they're on is set to Registered for example then public users can't view them.

Are you having issues selecting the fields when editing your userlist when setting fields to display in the userlists columns or have you already done that and it's just not displaying on the userlist? If you can't select the fields then they're either unpublished or not set to display on profile. If it's not display on the userlist despite being selected then it's usually an access issue with the tab (e.g. tab not published).

Don't know what more to suggest beyond review the fields parameters carefully and the parameters of the tabs they're on if they're not displaying. If you've CB Privacy or CB Conditional for example then either could be responsible for suppressing a fields display as well. By default they will display perfectly fine so something was changed from the default settings to prevent their display. You can provide a link to your userlist in a confidential tag if you like and can review the HTML to see if they're even attempting to output.
