"Question: Isn't a none-breathing race suppose to be fine with any atmos type?
Can there be a race the breath every kind of Atmos?
I mean, look at the Dopplergangers, droids that don't need atmos to live, so they should be perfectly happy with any kind of atmos since they don't need any........"

Well, there is pressure. Any vacum-adapted race would probably not do well in earth-normal atmospheric pressures.

There is a lot more than just the gases of the atmosphere. As Phoenix said, None-breathers require a vacuum. Planets with an atmosphere do not have a vacuum, they have lots of pressure. So, they need domes in which to create a vacuum on a planet with an atmosphere. Of course, many other things should be factors too, like Radiation levels, Heat, Gravity, etc. to make colonization more realistic, but those aren't modeled in SE4.
