Desert Exiles:

Response: After a Reinforcements event card is played, draw a card.

How many times i Can activate this response?

Can I draw 3 cards up to the limit?

Are you asking because of draw cap? (max 3)

Or because of one response per trigger rule? (You can use it only once per Reinforcements event)

What if I have 2 of them in play? Can I draw 2 cards (by activating the response of each Desert Exiles) with only 1 reinforcement played?

Yes, because that's two separate cards, thus two separate responses.
