It boils down to one's perspective on God and Heaven. I believe heaven is not a physical place, but an attitude with respect to God, the Almighty, the Great Pumpkin or whatever one chooses to label the great force behind our Universe and its creation. If one is with God, which it appears several you described are not, then they will put themselves in their own hell. If one chooses to remove themselves from God, then, buy definition, they are "out of the light and into the darkness". A euphemism for Hell. Like Heaven, Hell isn't a physical place either.
FWIW, I think, given eternity, that eventually everyone ends up in Heaven. How long it takes is up to them since it is up to each to determine when they will see and come into the light.
