Also - how does the Demoralize option of the Intimidate skill interact with causing a shaken condition using the Dirty Trick combat maneuver? Or with the 'rattling strike' hunter's trick from the skirmisher ranger archetype?:

Pg. 321 of the Advanced Player's Guide, under 'Dirty Trick':

"If your attack is successful, the target takes a penalty.
The penalty is limited to one of the following conditions:
blinded, dazzled, deafened, entangled, shaken, or
sickened."

Pg. 128 of the Advanced Player's Guide, under 'Hunter's Tricks' of the Skirmisher Archetype for the Ranger Class:

"Rattling Strike (Ex): The ranger can use this trick as a
free action before he makes a melee attack. If the attack
hits, the target is shaken for 1d4 rounds."

Is it possible to use two dirty tricks in a row to cause an opponent to become frightened? Can you use two rattling strikes in a row to do likewise? Can someone perform a rattling strike and then follow it up the next turn with a dirty trick to cause the opponent to take on the frightened condition?

From the Advanced Player's Guide, pg. 128, under Hunter's Tricks:

"A ranger cannot select an individual trick more than once."

This may seem like roundabout reasoning, but it appears to me this statement would be unnecessary if the total uses of all the hunter's tricks were equal to x = "a total number of times per day equal to 1/2 his ranger level + his Wisdom modifier". It's only when each hunter's trick can be used x times per day that there would be any point to choosing a trick more than once.

Of course, my character is a ranger so I'm a little biased!
