I agree on all others except #4, which is under debate.
Don't think either Magnolia or Parula fit, Magnolia since we can't see any markings on the underparts. I think parula would show more color/brightness to the upperparts and wing bars. In fact, I don't think the very dull wing bar(s), olive upperparts, and general appearance fit any Neotropical warbler.
Perhaps this is a Cuban Vireo? Gray legs fit, but fit other species as well. Cuban Vireo does have such a wing pattern and dull greenish yellow underparts. To me, the tail appears completely dull olive-brown. We can't see the bill at all, but I seem to see a large, dark eye through the foliage. Perhaps there are even pale yellowish lores visible, but I'm much more unsure on that. Even if the lores aren't actually visible, I think everything else fits Cuban Vireo.
Thick-billed Vireo is apparently much rarer in Cuba, and should show two bright white wing bars.
