I want multiple x2 cards in an x16 lane, and i wondered if that is even possible, due to power or chipselect or something. All i know is that I haven't been able to find a x16 or even x8 PCIe-card that splits it's lanes in 8 or 4 x2 lanes.

All PCIe links use a point-to-point topology, so each originator (the upstream port) must connect to one and only one terminator (the downstream device). Now, that downstream terminator can be a PCIe switch which can expose multiple ports itself. This is how many motherboards expose a large quantity of 16x slots, they insert PCIe switches between the slots and the root port on the CPU/chipset.
There may be some expansion cards available that contain PCIe switches which in turn expose multiple...

So you are saying you want to fit a few 2x cards into one 16x slot? Doesn't work that way. Gotta put each and every cards, regardless of how many lanes it is, in its own slot.
How many lanes you have total depends on the cards not the slots. You could have 2 16x 2 8x and 2 2x slots but if you only have 16x lane CPU thats it. You could fill up all 6 slots with 2x cards and you are only using 12 lanes total.
Cant fit like 2 2x cards in a single 16x slot if that is what you are trying to do.
mSATA is STILL a SATA interface and does not work over PCIe like M.2 does without an adapters.
M.2 uses actual PCIe lanes and requires an adapter or a M.2 Slots. M.2's don't use more than 4 Lanes.
Still not sure about your question there. Are you trying to put multiple items in a single x16 slot or are you tying to ask if a x2/4/8 can go into a x16 slot etc?
