I confused a little about serial port library example. Can I consider this like software uart example similar to arduino softwareserial library?

You can have still two instances of UARTE but there is almost no problem to connect Tx line from nrf52 to more receivers.
The only limitation that comes to my mind is related with current "consumption" of each node from Tx line. If there will be too many devices UARTE signal might have too big voltage drop to be correctly interpreted.
Do I understand correct.. We have 2 instance of uart for nrf52832 and 4 instance for nrf52840 chip?
No, 1 instance on nRF52832 and 2 instances on nRF52840
To be more precise:
nrf52832 = 1xUART or 1xUARTE
nrf52840 = 1xUART 1xUARTE or 2xUARTE
Thanks for clearify
