Photo is awfully small and grey, hard to be sure of anything.
There's one of the blue-and-yellow euphonias at upper center, e.g. thick-billed.
The bird above it looks a little fatter than the others, but it could be the angle. Possibly it has a yellow belly. Kiskadee? Flycatcher?
Bird left of that looks similar - perhaps yellowish belly, perhaps slimmer, but grey head eliminated kiskadee. Flycatcher? Tanager?
Bird at left edge has yellowish back and dark wings with bright markings. Oriole? Tanager?
Vertical bird at right of picture looks plain grey, but can't see it well. Could be, say, a palm tanager, but really it could be anything.
Two tiny horizontal birds below that one. Female euphonias?
