''There's no evidence to why the 6 humans lost their ability to save/load/reset is gone when Asgore put them in a glass jar. Why would the souls of the 6 humans would persist, while that of Frisk's is not?''

I answered this one while you were typing your response, I believe. :'>

For the bit about Toriel and remembering the others - recall that all monsters have dialogue alterations if no true reset occurs and if a save file (or reset) occurs. Asgore is not surprised when we tell him how many times we have died. Toriel says that she gets a sense of deja vu with every human that has fallen... and we know that she has seen all of them.

This either means that every human was, in some way, Chara or that every human has had the ability to SLR.

Amalgamates are monsters and do not have the physicality to manipulate time, as their being are entirely their SOULs. This is why Undyne recovers from death (similar to Frisk's SOUL in the TP boss fight), but cannot manipulate time. This is also why the six human SOULs grant SL ability to Photoshop Flowey - once reunited with a vessel, six SOULs are much more powerful than our (unactivated Chara/Frisk) SOUL.
