There are a few in Headquarters, five or six helpful ones on various streets and locations, and some bad ones guarding the docks and other places.
As far as the missing ones you have to save, there are three : one at the docks, one at the electrified building on Toupee Terrace, and one in a greenhouse above a large building on Balding Avenue. You must rescue them in that order, because each will give you special equipment to save another one or complete the quest.
