When the humans explore a new tile, what if it cannot fit? Can the Demon player place it on a previously revealed unexplored passage?
I've yet to see that happen, but if it did, I'd follow the rules for Dead Ends on page 12 - discard and draw another tile.
The Demon Threat phase ablities in red.. is it true that you may only use 1 per round? But the abilites in black can be used more than once a round?
Yes, that is correct.
On a side , whilst I remember, there is a map tile that lets the demon player roll an extra die in his threat phase... in a game tonight we had 2 of those tiles in succession and one of the humans explored both. Does this mean the demon could have rolled 2 extra threat die?
Yes, 2 extra threat dice on the following turn.
