Yes, this should be possible. You would just need to configure each Streaming Bridge to use a different port using the ATEM Setup utility over USB (the Streaming Bridges would all use the same public IP address, assuming they are on a local network behind a firewall using NAT).
This setup is described on pages 130-132 of the ATEM Mini manual:

The ATEM Setup utility will attempt to configure port forwarding on the router using Universal Plug and Play (UPnP), but this may or may not work. Depending on the router and its configuration, you might have to manually configure port forwarding for each port used to the corresponding internal IP address for the Streaming Bridge on the local network.
In terms of what ports to use, it's kind of up to you. Port 1935 is the default for RTMP, but some other streaming platforms use other ports. Facebook Live uses port 443 (for RTMPS), for example, and I've also seen some services use 1936, 2935, and 2936. The main thing is to avoid any ports that may already be used by other well known services (such as mail or web servers) that are publicly accessible through the same IP address. Here is a decent list of some commonly used ports for different services, that you might want to avoid: https://web.mit.edu/rhel-doc/4/RH-DOCS/ ... ports.html
One other thing to note is that some ISPs may restrict inbound usage of certain ports, in part to discourage people from running public servers on consumer-oriented internet connections. If this is the case, you would need to stick to ports for which the ISP allows inbound connections.
