1- could we make copy of the functioning SD to another SD?
2- does SD have to be same size or different size does not matter?

How did you copy?

A copy in Windows explorer won't work. Windows doesn't even see the second partition, because it's EXT4 format.

You need to use a disk imaging program, such as Win32imager. Have a look here:

Or you could do it the sensible way, on the Pi itself.

Boot up the Pi, put the new (target) SD card into a USB SD card reader/writer (plugged into the USB port on the Pi), then do:

dd bs=1M if=/dev/mmcblk0 of=/dev/sda

(assuming the USB SD writer comes up as /dev/sda, which it should do)
