Is there any time OR exceptiopns where Life safety and critical loads can come out of the same Branch circuit panel?? I think not but just asking. Also circuits not listed as Cirical in the NEC should not be in the Critical panel also right.again I think not but just asking.

On a military base! Per uniform facilities criteria (which references the NEC as code, btw) There's no separation of life safety from other essential mission loads. If it requires generator, it's on one switchboard. Sometimes two, for redundancy.
Generally speaking:
Emergency Power = generator
Critical Power = UPS
