To me it sounds like it's the eggs that were to blame and not your incubating skills or the power outage. I'm not sure about quail, but I can't imagine they'll be that much different to chickens. 83F for a few hours shouldn't wreak that much havoc with healthy fertile eggs. Neither should the humidity drop, if it was for less than a day.
D) Totally dried up yolks: Sounds to me like very old eggs. Or poorly stored in extremely low humidity.
E) Runny yolks: Sounds to me like infertile eggs. More likely to be that than very early deaths anyway.
B) Almost fully developed, organs on outside: Sounds like a deformed one that would have died no matter what.
