Short distance between transmitters

Hello. I am using LoRa E32 900T20D module. My project has 6 LoRa modules in one box. Antennas of LoRa modules are located at a distance of 10 cm from each other. These modules used at fixed mode and all 6 LoRa transmit to a receiver within 1 km. These modules receive and transmit data at different times(alternately). At the same time, modules doesn’t data transmission and receive. My question is that when 1 module is transmit datato a receiver 1 km away, does it have a negative effect on the 5 modules next to it? . Will there be problems(burn) in other next to 5 modules?.Thanks in advance
