The first two are at the Dragonheart regiment camp. For the third, go straight south from the Dragonheart regiment. It's near a rock outcropping, surrounded by Army of Light people. Fourth is just north of Dragonheart regiment, in a cluster of cabins. Fifth is in the building with Darvin Oggleby, south side of the zone.
There are several of these scatered about. The ones I found are at:
