For example when 5 users login using login.php simultaneously, is a new database connection created for each of the five users?

PHP does not support connection pooling. phpBB does have the option of using mysql_pconnect. pconnect however is not pooling, but a primitive form of re-sharing a database connection. Related: Connection pooling in PHP
To answer your question: Yes, PHP applications open a new connection each time.
