FDDI - all 14
Ethernet - 14 but only the first 6 can be actively used as the
chips in the modules can only talk to the first 6
channels.
Token Ring - none the 2 Token Rings are located on the upper
connector.

With modules such as the DECrepeater 900FP you can group ports
together. If you do not connect them to anything else then they
are a LAN and traffic can go from port to port (in the group) but
cannot leave the module or talk to other ports.
If you take ports 1,2 and group them with ports 3,4 in the 900FP
then the users on the fiber ports can talk to each other but cannot
talk to any of the other port pairs and maybe not onto the backbone
or backplane.

No. Generally only an AUI port.

I saw the codes posted somewhere in this notes conference but can't
remember where.

sure, from note 605
hope that's help you
