Whats the name of these connectors?
Those are PCB to FPC or PCB to PCB mezzanine connectors. There are several manufacturers and pitches of these connectors. One manufacturer that comes to mind is Hirose, they have a whole range of them. Samtec also makes them, and I believe Molex makes them as well.

I don't know if it is a real standard, but many companies call parts like that a mezzanine connector. Two common uses are flex circuit-to-board and board-to-board. Some are written into standards like VME, CompactPCI, etc. Search for 'mezzanine card' to see many examples.
