Your telnet lines are vty lines. The routers ship with lines 0 - 4 and some routers 5 - 15. You generally land on vty line 0 when you're the only person telnetting into the router. There are some cases that services, in the case of EEM, will also use vty lines in the background.
There are 2 enable passwords: enable password and enable secret. Once the enable secret password is configured, your enable password will no longer be used. Enable secret is MD5 encrypted, so it's hidden in the running config whereas the enable password method requires service password-encryption to be enabled in order to encrypt the enable password. There are many tools online that can decode that type of encryption though; always use enable secret.
You can assign usernames the same way: username test password test OR username test secret test....same principle as above.
