Are you new to TV shows? There are three types of a cast:

1- series regulars: they appear in most episodes and their names are always written even if they didn't appear.

2-recurring characters: they appear alot (not in most episodes) but when they don't appear they are not credited.

3- guest characters: they appear in few episodes and then they leave, they are jot credited if they don't appear.

And the series regulars of PLL season 4 are (in order): spencer - hanna - caleb - aria - ezra - ashley - emily - mona - alison.
