Q: so each 3 cards have same efect of burning card from minion. so if in table have 5 players: A B C D E, A play Pulled Fangs (or one of two another cards) on B. if B want to burn this cards,that count as undirected action. what if example D want to burn these cards,is that count direct action on B,because is card atached on B,or is also count as undirected action,and D predator and prey can block it?

From the rulebook:
A minion card in play is controlled by the controller of the minion it is on.

Meaning that if the controller of the minion attempting burn action is the same as the controller of the minion with the card being burned, it is an undirected action, otherwise it's a directed action against the minion's controller and only they can block, by default.

Note that some cards have "you still control this card" card text (e.g. Aversion, Deep Cover Agent). In this case, the controller of the card is obviously the player who played it, regardless of who controls the minion it is played on.
