I'm American, but my pronunciations for a couple of these are influenced by the fact that I speak French (not fluently, but my pronunciation is pretty good, so that's what counts here).
Jacqueline -- JAK-ə-linn, JAK-linn, zhah-KLEEN
Genevieve -- JENN-ə-veev (if it were Geneviève, though, I'd say zhe(n)-VYEV, with (n) meaning a nasal sound)
Ephraim -- I don't actually know how to pronounce this name, so I'd guess that it's EFF-rehm, EFF-rəm, or eh-FRAIM
Tamara -- TA-mə-rə, TAM-ə-rə (although the second syllable is supposed to be stressed, isn't it? tə-MAH-rə, then, I guess)
Anastasia -- ann-ə-STAY-zhyah
Joel -- JOLE (rhymes with coal)
Madeline -- MAD-ə-line, MAD-ə-linn (either way, it's three syllables for me)
Andrea -- ANN-dree-ə
Renee -- re-NAY (completely French pronunciation)
Serena -- sə-REE-nə
I hope those make sense (especially with all of the schwas)
