You can have multiple secrets, but only one of each one at any time (i.e. you can't have two Explosive Traps out at once). While this often doesn't matter, the secrets will technically activate in the order they are played, such that if you first played Misdirection then you played Explosive Trap, and if an enemy minion attacks, the MD will proc first. It hasn't been clarified if the Explosive Trap will still trigger if the target is md'd away from the enemy hero.
