Well it’s a really mixed group of people all buried in a common pit. If they were Allie’s they’d have been buried in less heterogeneous groups according their own customs. Some may have been slaves but that doesn’t seem to be a common situation outside of Sparta and some rare occasions. It’s well documented that there were a lot of mercenaries used in the Mediterranean at the time. The Greeks didn’t write much about their own use, but it makes sense. You’d probably want unit types other than hoplites in a large conflict, and specialized mercenaries are a great way to achieve that.
