We think ccp n hcp are the same. They are. But one small difference. The unit cell of hcp is very different frm tat of ccp. Even i made the same mistake. The unit cells r the only thing different from both. Refer any book for unit cell. I think u must be knowin anyway.

The qsn is not particle per atom. It is atoms per unit cell.

watch in the second series of the HCP diagram
more atoms can come beside the 3 atoms which will increase atom per unit cell
this confusing
