At home I have cable high speed internet, an access point and 3 computers connected to access point. The access point have a IP address, XXX.XXX.XXX.XXX. The 3 computers have static IP addresses as 192.168.0.30, 31 and 32.
How can I connect to any of these computers (lets say telnet to one of the Linux machine) from out side world?

You would need to set up port forwarding on your networking hardware from a specific port number on your public IP address to a specific port number on the Linux machine. Telnet typically uses port #23.

If your cable broadband service uses a dynamic IP address then you will need to subscribe to some dynamic DNS service so that people on the outside can connect to your network using its current public IP address.

EDIT: You need to check your ISP's usage policy to make sure they allow running any type of server on your account. If not permitted, they may block incoming connections on some port numbers.
