Hi,
Can I connect 40-PIN RIBBON CABLE in A20-Olinuxino-Lime2 connector headers like GPIO-2? I dont know how connect A20-OLinuXino-LIME2-UEXT to connector headers!!
Yes. Anything that fits will do.
Olimex make things such as https://www.olimex.com/Products/OLinuXino/A20/A20-OLinuXino-LIME2-UEXT/open-source-hardware
which looks to work.

The cable is this one: https://www.olimex.com/Products/Components/Cables/CABLE-40-40-10CM/
JohnS linked the adapter (it also adapts the 0.05" step header to 0.1" step one for easier access to the signals).
Also if you want to solder some wires consider this fitting connector:

The A20-OLinuXino-LIME2-UEXT is useless to me because i cannot connect it directly to GPIO extension headers: GPIO-1, GPIO-2 or GPIO-3!
So my question is: can I connect CABLE-40-40-10CM directly in GPIO-1, GPIO-2 or GPIO-3?
One of pin connectors is 0.1 step and the another is 0.05?

Yes. It can be connected to any of the 40-pin GPIO rows. Including the LCD connector. You might need to perform some wire tracing to get the proper layout.
One of pin connectors is 0.1 step and the another is 0.05?Yes, exactly. One side of the adapter is 0.05" and the other is 0.1". Just don't forget the cables.
