You should start with IP addressing. Each of your machines
should have something like this:
address: 192.168.12.33
netmask: 255.255.255.0
gateway: 192.168.12.1
Where only the last octet of the address (the 33, above) is
different per machine.

A switch is a layer 2 (physical) device which selectively directs
ethernet packets according to their MAC addresses. That's what the 5
and 8 port switches are.
A router is a layer 3 (IP network) device which selectively directs IP
packets (which are encapsulated by the ethernet packet) according to
their IP addresses. It will need L2 ports to send those packets onwards.
A combined L2/L3 device is usually implemented as a small number of
routed interfaces, with one or more of those routed interfaces going to
an internal switch which offers multiple external ports.
Your TMO device:
routes between a 5G modem,
a wifi modem (deactivated), and
either
two ethernet ports
or two ethernet ports on a switch
