I see similarities between the first two videos you posted at end so I believe those are true because you can notice that they are both the same size not really tiny or small and they wobble/walk the same way. I find that to be incredible that they are almost identical in that aspect. As far as the Mexican videos go those gnomes/duendes were a bit too fast for me to see and the videos were really blurry. urgh!!! I hate blurry pixel videos where it's hard to see crap man all I saw was fast little tiny feet and a hat but why are they so small in that area? but boy those kids were sure scared:)
