Items are played immediately in that you have to immediately give the item to someone. After that, the hero holding the item can use it whenever they like and as often as they like. As far as I know, there is no limit to the number of active items on a hero (subject to the limitation around number of items affecting the same stat which you already mentioned).The key thing to bear in mind here is that items cannot be traded between heroes. By forcing you to play the item treasure card immediately, it means you can't hold onto the item and wait until you see who will benefit most from the item before giving that item to that hero.
