#1 and #2 are US made Classic Arms kit pistols. First one as you said, is a New Orleans Ace. Second one is called a Snake Eyes. Both are still available.
http://www.possibleshop.com/pistol-classic-arms-kits.html Probably worth in the neighborhood of $75 & $100 respectively.
#3 was imported, not made, by Armsport. They were importers in the '70s of inexpensive foreign made sporting goods, optics & muzzleloaders, who have since gone out of business. Hard to say who made it, maybe Jukar, Ardesa, Dikar. Typical of the Spanish imports, it's a knock off of a popular US design, in this case the Thompson/Center Patriot. Quality can vary, some of the earlier ones were poorly made, none were what you'd call first rate. bigblock said $150, so go with that.
