How do I connect simultaneously both MFRC522 and nRF24L01 of Arduino NANO?

3v3, D11, D12 and D13 pins are conflict with each other..

and than read ID number and send via nrf24 (simple code please)

No, they don't. The pins 11, 12, and 13 are the SPI bus. Any number of devices can be connected to the bus, as long as each device has a separate slave select pin. You need to set all the slave select pins appropriately, to define which device to talk to. Most libraries handle this automatically.
