"all it is is the number of simultaneous remote connections allowed"
so that means I can also use "line vty 0 1" ?
And if I have "line vty 0 4" what happen if 2 people configure the router at the same time? no conflict?

Yes. But keep in mind that you can't select the line you will connect to when you telnet in. Which is why most people assign the same password to all the lines that can be in use.
And if I have "line vty 0 4" what happen if 2 people configure the router at the same time? no conflict?
As Nazsky said, no problem making changes. But if two people try to save the config at the same time, one will receive an error message. But it would have to be done at exactly the same time.
