[MCU] About the dead people after the snap

>!In Avengers Endgame, did the dead know when they were brought back by Iron Man? And secondly, how did the other avengers know that a fight between Cpt. & Thanos taking place? Sorry if these are stupid questions.!<

First of all, not a stupid question.  
Doctor strange seem to have been the driving force, he was the only one who knew what was going on. So he called his sorcerer cliq and told them to gather every warrior who wants revenge against Thanos and i believe thats it.
