The first photo is definitely green fibre They are ball grid array chips As MLS pointed out they are commonly called corner or tab chips because of the gold corner. Soldered surface mount chips come in two designs the bga like the first photo and peg pin PGA (pppga or 3pga). And will always go as green fibre. But you'd have to turn one over to know for sure.
What I think MLS is talking about in the post is Called LGA. Land grid array. They have dozens to hundreds of tiny gold squares on the bottom and almost always a heavy partially integrated spreader. And it's highly recommended not to attempt to remove the spreader (ceramic pinless without spreader will get pentium ceramic rate) because the vast majority have components as part of the spreader as well. So even if you can remove it without cracking the CPU you reduce the value considerably.
The second photo is bga with a metal spreader, looks like aluminium or shaved copper. These are up to Chris but are probably pinless and may get green fibre with metal. These aren't common enough to get a specific classification and it varies by chip.
The third photo looks to be pppga. Those you need to post a reverse side for me to tell.
