Render - Multiple Models in 1 File?

Hey all!

Wanting to make a render for all of the skins we are planning to have, but I am most likely being silly and missing something - when I import -> Import Open Project, they seem to share the same UV, and im unsure on how to separate it.

The images provided are what I want to have on the same file, as well as what happens when I import.

Thanks in advance!
