Any wheel, oem or aftermarket, can be placed in ANY position on the vehicle, allowing for routine periodic tire rotation to ensure even wear.
Not sure what "divots" you are referring to in your photos???
Unless two of the wheels you purchased were somehow custom modified for a specific reason, like perhaps to allow for use with a big brake kit??? Even so, such a mod would affect the integrity of the wheel.
Otherwise, it shouldn't matter where they are mounted.
I going to assume that two of your wheels may just have a different design from the factory, and possibly for the purpose of preventing seizing of the wheel to the hub?
Maybe someone else here can verify that theory as the reason for not being completely flush at the mating surface between wheel and hub? That is the ONLY thing that makes possible sense for the difference that I can imagine.
