We are running SQL 2005 Failover cluster with 2 active nodes and 1 passive.  The active nodes have a default instance and 2 named instances on one active Node and 3 named instances on the other active Node.   I noticed that in addition to the default intance running on 1433 (which is the 'default' for a default instance), 3 other instances have been set up use static port of 1433.  Should the named instances be using port 1433?   I need to modify another named instance to a static port #... what port numbers should I be using?  Should I use 1433 again?  Thank you.

It does not matter.  You can use which ever port you want.  

I would recommend using a different port number just so that you have more control (you can connect to the instance without the instance name: server,port).

Setting the port to something other than 1433 can be useful for security reasons (having a firewall only allow traffic from certain address to a specific SQL instance) or for connecting with legacy programs that don't connect to a named instance properly.
