Social Flycatcher

Yes, looking at the second one, it also could be Pitangus sulphuratus. Actually I would even tend to Great Kiskadee, without being that sure, because I cannot see the little hook at the bill. Good eye, kaygraco!

It could be a Great Kiskadee (Pitangus sulphuratus), but as @bayucca says, you need a clear shot to identify it.

This is a Flycatcher. Could be Myiozetetes similis, Social Flycatcher, this just from shape and possible smaller size than other. For an ID of this one we would need a clear shot of the head/neck and the bill. I know it is not always easy to get these shots, but maybe you have some more in reserve...
