That’s easy! There are many mansions ( levels, or realms of consciousness). Reincarnating souls can go to any of them. At least that’s how it was explained to me in my eastern days.
And yes, there are souls waiting for bodies - it is a conscious choice ( some say a fight for, even) the opportunity to reincarnate into a human body. There are no victims in reincarnation - it’s all your choice- God being the absolute gentleman that he is would never put a soul in a body without it’s consent.
When the kids used to complain that they didn’t ask to be born, I used to say - yes, you did, and right here, too. End of victim story.
Not souls!!

MormonISM has 3 levels of Heaven and not really any Hell.
Most MORMONs will end up on Level Two.
That is if Brigham Young is a False Prophet:
"Now if any of you will deny the plurality of wives, and continue to do so, I promise that you will be damned;
and I will go still further and say, take this revelation, or any other revelation that the Lord has given,
and deny it in your feelings, and I promise that you will be damned.
Brigham Young - JoD 3:266 (July 14, 1855)
Otherwise; they'll end up someplace they didn't think it was POSSIBLE to go!
