The warbler on the upper right is certainly a Yellow; the one on the lower left suggests a Wilson's judging by the face, but the tail looks more like a Yellow so it's likely it's a female Yellow accompanying the male, but it's hard to be 100% sure from angle of the picture which doesn't show the top of the head.
The kingbird looks like a Western Kingbird. I'm pretty sure I see white outer tail feathers in that first picture, and the bill isn't nearly large or heavy enough for a Tropical Kingbird. Plus, as you pointed out, you are way out of range for a Tropical Kingbird, in fact, while they are extremely common in central America, you're lucky to see one in the U.S. even in their very limited range in south Texas.
