The other SOULs had to have had determination because it says directly in Entry 5 "I've extracted it from the human SOULs. I believe this is what gives their SOULs the strength to persist after death." There is no way for Alphys to have gotten the determination if the others did not have it, and it's the basic reason human SOULs are strong enough to not disappear like monster souls.

As for resetting time, it's entirely possible that the other humans were able to do it but got stopped by some monster enough that they eventually gave up. That's what Sans tries to do to you when you fight him: you have the ability to keep resetting time forever, but he's trying to make it not worth coming back by frustrating/boring you into quitting.
