yes, they are metal, and they use other reference names on the blister… they are sold all separatly
the reference go by the names “Orc-1” “Orc-2” etc etc… I have some links for some of them but I can’t find back the original advertisement sheet from Time Machines to make the “unoffcial” conversion”
indeed these were not called mordor orcs, or gondor army, but “non tolkien” names… which was a good example of a possibility of mithril figurines being distributed outside mithril, without tolkien licence…
