No it wasn't just the demon generals (whom are Demiurge's) but also high ranking undead NPCs that Shalltear has for example, so if you read Vol.7 Prologue it says all high ranking NPCs from floor 1-7 that were present were all on average above level 80 and there were over a hundred of them, also that's not including NPCs from the 8th floor, so in Nazarick there could very well be a lot more level 80 and above NPCs.
