I think if we have a liquid containing all of these substances and are distilling it, the lowest boiling point substances will distill first. And that is the substances with the lowest molar mass and the lowest intermolecular forces of attraction. So

H2 will distilled first, then N2, then O2, then CO2.
I hope this will clear your concept.
