I'm sure this question has been answered many times.... But if I use an ability on a follower, then it gets destroyed, but I bring it back into play right afterwards. Can I use its ability again? for example I use daidoji Gunso to lower the force of card A. Opponent destroys Daidoji Gunso I bring Daidoji Gunso back via Castle Barracks (can I now use Daidoji Gunso to lower the force of a card again?)
Dead followers and such

No, you cannot use the Follower's ability again that same turn. The card has not "forgotten" that its ability was used; in order for that to happen, it must be both out of play AND face-down (emphases mine):
http://rules.l5r.com/Effects#Tracking_rule: "“Memory” of the status of individual cards ends when the card enters a deck or a hand, or otherwise becomes both face-down and out of play (such as after a card in the deck or hand is shown). This includes dishonorable status, ongoing effects, and whether or not an ability has been used."
(Side note, about your topic title:
Only Personalities in discard piles are ever referred to as "Dead".
http://rules.l5r.com/Physically_marked_card_states#In_play_and_out_of_play: "No distinction between destroyed and discarded non-Personality cards is made while they are in the discard pile; all such cards have the state "discarded."")
