Hello friends, I wanted to ask you a question regarding lorawan sx1276. I wanted to know if only the master can send messages to the slave, or also the slave can send messages to the master, as an acknowledgment.

As I can see the SX1276 has an SPI interface. SPI can be full duplex, the CS pin selects the slave device and then on the clock pulses the slave transmits data on the MISO line. (Master Input Slave Output).
So answering your qustion shortly: yes, it can.
