I. This proton is next to a CH2 group and will have 7 peaks (n+1 rule, where n is the number of protons on neighboring carbon atoms, in this case n=6).
II. This proton is next to a CH group and will have 2 peaks (n+1, where n=1).
III. This proton is next to a CH2 group and will have 3 peaks (n+1, where n=2).
