An RFC1918 IPv4 address should not be used to generate a 6to4 address; it doesn't make any sense. Addresses of that form contain no information describing how the packets should be routed to your network. It's as if I mailed you a letter with a destination address of "Jack's Living Room" There’s nothing wrong with the generator, you’re just misusing it.

If the addresses are incorrect, they are incorrect from the address generator i used.

First, you can't generate an IPv6 prefix by concatenating 2002:[private IPv4 address]. There's no way that will be globally unique. Second, if you put your hosts on different /64s, they won't be able to talk to each other. Third, you've provided no means by which the hosts can communicate to the external world. This setup will never let you ping ipv6.google.com, or any other site on the Internet. Your IPv6 prefix should either be: 1. Assigned by your ISP, or a tunnel broker. 2. A 6to4 address, calculated from your global IPv4 address. 3. A unique-local address, starting with "fd". This one won't let you access external sites. In summary, I suggest you figure out what you're talking about before sharing the knowledge with others. This tutorial is mostly wrong.
