Dear all,
only one simple question:

During my turn:
for example I have on map 3 pinky and used event card FEROCITY: Can I used this one card for all pinky demons, or only for one pinky?

My gut instinct is to say only the one, but I don't have card titles or effects memorized and my game's been put away for a long time (nobody to play with ><) so I can't say for sure. If you can give me the card text I can give you a more informed answer.

for example:

I have in my hand only last one event card: FEROCITY.

Now it is my turn: I use PINKY DEMONS (currently on map I have 3 figures of pinky demons)

So If I used card FEROCITY, its effect is only for one pinky demon or all three pinky demons?

Right, what I'm saying is I need the card text of Ferocity.

On ferocity card is this text:

"Play this card after a demons perform an attack targetting adjacent figure. The demons may immediately perform 1 additional attack. Then, it becomes stunned.

I'm pretty sure it's just 'demon', singular, in which case yeah it would only apply to the specific Pinky. (I actually don't think there are any cards that apply to an entire activation group of demons like that, anyway.)
