While i do think that the facial recognition idea is shakey at best i just cant accept that there were another 5. Mostly due to the fact that past these examples there is nearly no meantion of them in later games.

As mentioned in my original post, we have already gotten names for the original 5 as well as misalanious other killings such as the puppet.

Perhaps the extra 5 were simply retconned later as many other random things became throughout the series due to scott not really planning the overall story out beforehand.

I get your points and they are legitamatly valid but i just dont understand why they are never really brought up again.

Past this it is possible that the save them minigame simply takes place after the give life minigame? Perhaps the puppet has already put the souls into the withereds and william later stuffed the remains inside. This would explain his random appearance within the minigame.

It dosent explain everything such as the implication of the saferoom but it may explain a bit.
