There are as many types of Paganism. There are no "general" Pagan beliefs, with anything really, and since it would be impossible for me to answer for everyone, I'll just answer for myself and let others do the same.
No, not at all. In my beliefs there is one afterlife with multiple steps. When we die, we shed our physical body and move to the next step. This is commonly called the astral plane and is the subject of interest for those who practice astral projection. We again shed our bodies, leaving behind an astral corpse as we move to the next step. There's more to say about the nature of the astral corpse but that's another topic. There is debate about how many steps/levels/planes/whatever there are. I personally have experienced three, so while I am more than open to learning the characteristics of others, I only work with the three I know. The third of these steps is the final one (with any others, if they exist, being between the astral plane and this final step). This is characterized by the iconic gates which cannot be passed by a mortal without falling into death. While we are able to roam the astral plane without completely disconnecting from our bodies, we can only reach up and touch the gates of the final afterlife. There is also some debate surrounding this final afterlife, with some claiming that the spirits we call back in necromancy being only astral corpses clinging to life, while others claim we sometimes pull astral corpses but are also capable of speaking to the dead themselves beyond the gates.
Wikipedia defines Sheol as "a place of darkness to which all the dead go, both the righteous and the unrighteous, regardless of the moral choices made in life, a place of stillness and darkness cut off from life and from the Hebrew God." I guess this would be closer to the afterlife? I mean, yes all life goes to the same place, but it isn't stillness and darkness I'm sure. In fact, we have no idea what it's like, we've never been there. The only thing we have is how the dead speak, and they seem to not mind. My guess is that the afterlife is much like our lives now. It's neither good nor bad, it just is.
All life follows the same steps, actions, beliefs, personality, none of it has any influence on what happens after death.
I take more of a classical occultist approach to the afterlife and my beliefs are heavily shaped by my practice in necromancy. Every Pagan will probably answer these questions differently, so it's important to remember not to assume one of us speaks for all of us.
