I do so love to work with fey. I've been working on a project involving them over at Dicefreaks - I'd offer a link but the site is down and there is an imminent server move pending.
I like the imagination you've shown with these critters. Some mechanical notes: The honey nymph's honey should probably offer the effects of goodberry or a similar effect if it's so healthy. She has Diehard despite lacking the prerequisites. The llymha seems to be offensively too weak to merit a CR of 4 - seems like a low 3 at most to me. I'm not familiar with psionics and so I can't really offer any suggestions regarding the tromlui's mechanics.
As for the fluff, I see some purpose in the honey nymphs, but you haven't really provided much in the way of purpose or culture for the other two. Personally, I see fey as aspects of nature, and so I don't see 'slum' as a very appropriate area of concern for a fey.
