Hm, I think they look ok. It's natural to lose a leaf or two in the winter. They aren't at all crowded in that pot either. When there are so many crowns in the pot that you can't see the soil, it's time to re-pot.
I'd leave them be for now, keep them on the cool and dry side for another month or so, then add a few handfuls of fresh potting mix to cover those rogue roots that are up out of the soil, and a teaspoon or so of slow-release plant food. Start watering more, keep them in bright shade and gradually warmer temps and see what happens.
Don't despair if they don't bloom this year. They look like fairly young plants to me and they are very slow growing at their best. Mine has some leaves that are nearly 2ft. long - this is the plant that hasn't bloomed for 3 years, but I have great hopes for this spring!
