The fcc figure is clearly incorrect because it is not the same at the two points labeled Gamma.  
 The free electron bands can be drawn for every Bravais lattice. Hcp is not a Bravais lattice. The Bravais lattice of hcp is hexagonal and there are two atoms in the basis. I suspect that the figure labeled as the free electron bands for hcp is intended to be those for hexagonal with an a/c ratio corresponding to hcp. This figure is also clearly incorrect since there can be no peaks or dips in the bands between the symmetry points like the ones seen in this plot between Gamma and K.
