Hello BadVolf !

1) You need to have the same template (Protean for example), the same mix (for example this one https://una.io/page/view-discussion?id=2726), and place it to the column with the same width.

2) No, it doesn't. It is still a paid option.

3) Via the Studio->Pages->Persons->View Person area you may add / enable block "User photos" and customize it via CSS styles area of your template mix.
