At one university where I studied at for a bit around the period of 2009 - 2012, they had and, judging from their Wiki, still do have, finger daemons running on most Linux servers and workstation -- perhaps even on all of them. Furthermore, the vast majority of workstation computers at the department for informatics and at the department of mathematics are running RHEL, so it's not just a handful of computers. As for how many were actually making active use of finger and in particular .plan files, that was probably just a handful of people. I was one such person for a while after having learned about it and thinking it was kind of neat, but I eventually gave up on maintaining my .plan file and focused on other ways to share things.
