I'll bite, current lineup (minus #7 I didn't even know I had one left)
1, 2, 4, 5: Atomizers. Use for dripping (putting drops of liquid directly on the coils). 1 is a regular joye atomizer, 2 is an H.357 with a drip shield. 4 & 5 are rebuildables (Phoenix XL and something my wife won in a raffle?), they can be taken apart and the coils can be rebuilt using wire and a wick.
3 is a DID Clone. Also rebuildable using stainless steel mesh and kanthal wire, holds ~2-3ml of liquid in the tank section.
6 is an XL cartomizer (with flange at base, have some without but they're sealed in plastic still). Steel tube that has a filler material in it surrounding a smaller "fabric" tube that contains a coil. Liquid is dripped into the outer filler material and that feed liquid to the inner tube/coil. Holds ~1ml. This one is 45mm but you can get them in 35mm (and larger) also.
8 is a cartotank. Clear tank that has a cartomizer inserted. Cartomizer (same as #6) has holes punched/drilled into the bottom so liquid feeds directly into the carto. This one holds ~4 - 4.5ml.
7 is a Vision V3 clearomizer. Holds ~1.6 ml. It has a coil up top (~just below the metal band), and has wicks that go into the tank area that feed liquid to the coil.
9 & 10 are Vivi Novas. These are also clearomizers (you can see the wick more clearly in #10). 9 hold 3.5ml, 10 holds 2.8ml. You can buy replacement coil/wick assemblies (heads) so you don't have to buy an entirely new feed every time. The heads can also be dismantled and rebuilt using a selection of wicks and wire.
If you want I can open some of these and try to get closer pictures of the innards.
