You need to use a static IP address - one that is assigned to the nodes
permanently, and not managed by the cluster itself - for cluster comms.

Those can be private (ie, 172.16, 192.168.x.y, 10.a.b.c) etc, but the
cluster nodes must be able to reach each other via them.

You can, but there must be working multicast communication between the
nodes.

No, the only GUI is pacemaker-pygui. But there is the "crm" command line
shell too.
