Your best bet would be to search all of those entities on Wikipedia. They all have at least as much (usually quite a bit more) detail to them than anyone here could reasonably be expected to type up.
I'm not really a fan of the August Derleth inspired good vs. evil and elemental focus to the Gods; the whole point of the Cthulhu mythos was that they were elements of cosmic horror used purely as plot contrivances, not systematic and systemitized entities. That said, if you really want to use them as such, they all have write-ups in the d20 Call of Cthulhu game and the link Derro posted is as good a place as any to get deity stats if you need them.
