Does it include all types of particles? All atoms?

Thank you.

Nope.It applied only to electrons in atomic electron shells (the original 1925 formulation due to W.Pauli,which earned him a Nobel Prize).

It's not clear to me whether the Pauli Exclusion Principle (even though it might have been originally formulated as such) is only intended to apply to atomic electrons. I don't think that's important though.

More importantly - fermions, any particles (quarks, neutrinos, etc) have spins in multiples of 1/2, do obey Fermi-Dirac statistics, which says that identical fermions cannot be in the same quantum state.

Bosons, of integer spin, do not.

Is there any other then bosons that it doesn't work for?

Yes,ghost fields are fermionic (described by elements of a $\mathbb{Z}_{2}$ graded Grassmann algebra) integer spin fields...
