@spiritxiv it is very difficult to understand your questions and responses. Perhaps you should use your own language and use Google to translate it for us.
I will try to guess what you are asking.
A single 16x2 LCD, that does not have any kind of backpack, requires 6 Arduino digital pins to control it, one for each of these pins on the LCD: D7, D6, D5, D4, RS and EN.
If you wish to connect 4x LCD, the D7, D6, D5, D4 and RS pins of all 4 LCD can be connected to the same 5 Arduino pins. Only the EN pin from each LCD must be connected to a separate Arduino pin.
So for 4x LCD, 9 Arduino pins are needed.
By the way, the wiring diagram you posted would destroy your Uno.
