Sorry I'm so late to the party, Xoan.
The first model is a Space Marine sergeant with a power fist ("Space Marine Sergeant 1", part #010101103). If you bought the Ultramarines Tactical Squad that was released around the beginning of the Second Edition era, he came in that box, and was later available by himself in a blister. As there is no chapter-specific iconography sculpted onto the body,
he makes a fine Blood Angel.
The second model is an armless Second Edition Librarian in Terminator Armour ("Terminator LIbrarian Body", part #010104101). There are
different models from First Edition (
including a plastic one from an expansion to Space Hulk) and some for later editions that are now available in Finecast.
The third model is a Space Wolf Blood Claw ("Space Wolf Blood Claw 1", part #0805/2). They used to be available in a boxed set of ten, and later as blisters of two models each. These were phased out when plastic multi-part Space Wolves became available for Third Edition.
The next model ... ah, one of my favourites! Blood Angels Death Company! This particular lad is part #0424/3 ("Blood Angels Death Company Trooper 1"). I
converted one to be a veteran sergeant by sawing off his leg and giving him a bionic replacement sawed off from an old Epic Knight. They used to come in a box with nine troopers and a chaplain, then later sold as blisters of two models each.
Next is a Techmarine (70085/1) with a Servo-Arm (70085/3).
The next picture is blurry. It's obviously a Second Edition Devastator, but I think I can make out some flames embossed on the cuisses. Citadel sculpted some Legion of the Damned marines, including a couple with some wicked-looking heavy weapons (the heavy bolter has a skeleton atop it!), so this may be what that is, but I can't tell for sure.
The next model is another Blood Angel - "Blood Angels Death Company Trooper 2" (part #0424/4).
Then, another Space Wolf Blood Claw (part #805/4). If you're starting to think some of these models look alike, it's because they do. Many of the Blood Angel and Space Wolf models made during this time were simply the same Mk VI or Mk VII models for the regular marine range with added chapter iconography. Occasionally, they twisted the head in a slightly different direction, but it seemed pretty obvious to me what was what.
After that, a Second Edition Apothecary - part #70082/1 (like
this guy). We Blood Angels players have to call them "Sanguinary Priests" or somesuch now.
At some point (Fourth Edition, maybe?) players were required to mount their Terminators on 40mm round bases. You can tell the sculpts from earlier editions because the legs are much closer together to make them fit in the slot of a 20mm base. Both of these ladz are Second Edition Terminators (0441/3 and 70157/2). The sculpts were different from the First Edition ones - most notably in the robustness of the limbs and shoulder pauldrons, but also the addition of purity seals.
The next model is a Chaos Space Marine Terminator (70311/1) equipped with a heavy flamer (70312/22) and power mace (70311/20). The heads were separate bitz because they incorporated things like spikes and horns that made them difficult to cast as one piece. Depending on which arms you selected, some heads might fit better on some bodies than others. The backs also had slots where you were to insert rows of pointy bitz to use as trophy racks!
The last model is a generic Chaos Space Marine. Looks like part #70306/6.
