Yeah the easiest way you can do is add a bunch of if statements for the commands to trigger.
Code:
on *:text:*:#: {
  if $nick($chan,$nick,a,hrv) {
    if ($1 == !rules1) {
      ;code here
    }
    if ($1 == !rules2) {
      ;code here
    }
    if ($1 == !websites) {
      ;code here
    }
  }
}
