Going off the research I'm finding to the best of my understading these men were lower ranking Moors/soldiers. These paintings take place in the 1500s. By the 1500s the Moors werent as powerful (they were relatively weak if anything but still had knowledge the Portugese wanted) in Portugal as they were a few centuries earlier. In the early 1500s Portugal made contact with Japan and started to trade and eventually started to import them as slaves so these men might have been low ranking Moors who were either soldiers, servants or merchants.They look like servants tho
They are depicted as servants.
