Image 1474 (the green dragon thing) is a Grenadier Chaos Dragon from the Dragon Lords Dragon of the Month Club series II.
Image 1473 has a skeletal horseman and rider in the top left corner, also from Grenadier though I\'m not sure which particular set he came from (I have it, too, just don\'t remember which box he came out of). Same photo has a Citadel C-series fighter in the top right corner (circa 1986-89 or so). The rest I dunno.
Image 1472 has a Grenadier orc on horseback in the lower right corner, from the Fantasy Lords series (was a blister pack that also included a version on foot). The owlbear in the same image is definitely a Citadel ADD81 Owlbear (variant C). The lizardmen in the top left corner might be Grenadier as well, but I can\'t definitely place them as such.
Image 1471 is all sorts of Grenadier goodness. The two figures in the top left corner appear to be the two dwarf fighters from the aforementioned Chaos Dragon set. The slain dragon is from the Grenadier Fantasy Lords blister pack series. The skeletal archer in the lower left corner is from either the Grenadier Skeletal Mammoth or Skeletal War Rhino sets. The warrior on the ground (2nd from lower left) is from the Grenadier Dracolisk set (Dragon of the Month Club series II).
The red wizard looks like a Citadel C-series one, but I can\'t place it for sure. They made hundreds of variants in the C-series (some didn\'t have slotta bases either). I think the giant lich is a Grenadier Skeletal Giant (edit: blister pack from Fantasy Lords), but I can\'t be sure on him either.
Image 1469 definitely has two ADD56 Bugbears (a pose 1 variant D, and pose 2 variant D). Can\'t place the others in this photo.
Hope that helps.
