... and wheter they are mechanical or not, what switches do they have etc.

Imgur album.

Thanks.

All 3 cherries look some variety of g83 which is not mechanical. No idea about other two.

The trackball one is Cherry too (most likely).

Yeah g83 domes boards, the trackball one might be a g84 with ml, or could be a g86. The alcatel, I'm not sure either, but the only ones of alcatel I have seen with MX had Cherry doubleshots, so I doubt it does.

The model with the trackball appears to be a G84-5400, which has Cherry ML switches.

the last one looks like a G84-4400 with ML Switches as said. :

The one above that could be a G80-1502, which is an MX black based German health insurance card reader board.

But those do have the reader normally above the print/pause block, so this could also be an g83-6700, a rubber dome board, and basically the cheaper solution to the g80-1502. Depends how accurate the pic is.

above I 'ld say a G-83, rubberdome.

as the black one too.

The very top board has the Alcatel logo on it and I just stumbled over a video depicting an Alcatel board with Acer switches today:
