When trying to characterize the magnetic nature of different atomic elements, 3d transition metals have stood out in a few papers that I have read but I still have a few questions about them.

As I understand, the main characteristic which we should be paying attention to is the exchange energy.

Atoms Sc, Ti and V have a large radius, therefore they are too far away for noticeable exchange and therefore they have as paramagnetic.

Atoms Cr and Mn have perfect size/distance for indirect exchange, thus behaving like antiferromagnetic.

Atoms Fe, Co and Ni have size/distance appropriate for direct exchange, therefore they behave like ferromagnetic materials.

Lastly, Cu and Zn atoms don´t have any free electrons, then their magnetization is close to being null and thus they behave like diamagnetic.

If all of that is correct, is there any way that we can say that, for example, Fe, Co and Ni will have similar magnetic behaviour?

First I want to make sure I have understood everything stated above to keep on with my questions.
