I can seem to hear them all but only Lord of Riches (Host of many) and and Our Lady of Keys and Crossroads (She who brings us out of darkness) are the only ones whom I seem to have open dialogues with. The others seem to just pop in when they feel like it (which isn't often).
(as a note just about my way of referring to them, I always use epithets instead of 'names', I see it as more respectful but everyone addresses their patrons in their own way)
