Yes, they should be. I would recommend, you take one big machine as DB-WEB-COMBO (Database and Webserver) and the others just as voip-servers. So when installing the DB-WEB-system, you just say yes to MySQL and Apache, but no to voip-server. On the other servers, which should only act as voip-server, you say no to the former questions, but you say yes to voip-server and yes to "Is this an additional server in a cluster setup". If everytyhing goes right, you could check extensions-vicidial.conf, that's where vicidal generates entries "dynamically" - this is also where your phone extensions are stored for dialplan usage.
Since the voip-servers have to know about the database they all use, and in the databse is theconfiguration information of the other servers, they are interconnected per IAX2. If running into problems, just do a "asterisk -rvvvvvv" to see what's actually happening. Here you might find config errors becuase of mispelled strings - what actually never happended to me.
Let us know, how far you got !
