[Star Wars] How many separatists were there? If you would take away the droids, how many actual people were opposing the republic?

The Separatist Movement was thousands of worlds which aligned with Dooku, but the majority of the "senate" were leaders of guilds and corporations, not government. And their main motivation was money - the Banking Clan loaned to both sides of the conflict, and the Trade  Federation sold droids to their side. 

But there were standing armies that weren't droid based, and these were the most difficult battles for the Republic to fight (Geonosis, Umbara). And there were independant groups who were allied with the Separatists, most notably the terrorist group Deathwatch from Mandalore.
