I have setup 4 of the Waveshare SX1303 on 4 PI 4b, they are connected to the internet, but I wondering if they are capable of bidirectional communications between the other PI 4 that they are fitted on?

The Waveshare SX1303 boards cannot communicate directly with each other over LoRa. They must be connected to a LoRaWAN Network Server to exchange messages (with Pis talking through the server, not directly over LoRa).
If your goal is direct bidirectional LoRa comms between Pis (no server), you’d need to use modules like SX1276/78/92 or SX1262 instead.

What about setting up your own LoRa Server, that communicates with all the other servers and the 4 Pi’s. The Pi’s could then send messages to each other through the server, or is this not possible. I don’t know enough about LoRa.
Maybe a private LoRa network. Possibilities … ???
Cheers

Good morning Jim
I have 4 of the sx1303, I could set them up as a server for other devices to connect to, I have looked on the website for several devices like the sx1262 Lora Hat and the RAK11720, I could use these as my IRC type chat app for long range communications.
Kindest regards

Hey @DrScott297390 and welcome to the forums,
I agree with James46717 and ahsrab298840, setting up a centralised server to interface with all the nodes is going to be a lot less of a headache than attempting to have a mesh of LoRa nodes. Here’s a link to how to install a LoRa Server on debian / Raspbian.
That being said, if you love the challenge, there have been some similar attempts made in the past with ESP32 boards. While this one is currently no longer active, it might give you some additional ideas on how you could go about making one.
