I am assuming you are telnetting to your terminal server and opening a
separate telnet session for each connection.  The problem is that you only
have 5 vty lines configured.
There are a couple of solutions.
1.  learn the terminal server commands to allow you to connect to multiple
devices in one telnet session and toggle between them.
2.  Load a feature set that allows you to configure more than 5 vty lines.
