post 1 mentioned LoRaWAN but it appears you are now talking aabout a LoRa peer-to-peer network
in a peer-to-peer network all devices are equal and can transmit and receive - it would be the software which would add a layer to give a server/client network
you could certainly have multiple mkr1310 LoRa devices in such a network
you would program one of the devices to act as the server the other as client transmitting LoRa packets to the server
if client transmission is ad hoc they could corrupt each others packets
one way to fix the problem is for the server to poll each client in turn - see post some-help-with-lora-please and decimals-strings-and-lora
take care if you mix different LoRa devices in such a network, e.g. mkr1310 and TTGO LoRa32 SX1276 OLED - make sure they are all using the same LoRa setup parameters
