Wow, that really is an amazingly stupid fight. Not you, the people who are throwing around linguistic technical terms in a completely incoherent way while being belligerent to anyone who points out that they're not making sense.

I'm British so my answers to your questions may not be useful. But Julia I naturally pronounce with three syllables, can do two if I'm speaking quickly or if the person prefers that. Danya definitely two. Darya I have never tried pronouncing; I find it hard to get my tongue round a two-syllable version because my British r won't blend with the y very well.

Jewel: either one or two. I think I slightly prefer one, but either sounds ok. Poem: definitely two; I've only ever heard the single-syllable version used by people who were deliberately trying to caricature or mock other people's accents.
