1 and 2 are the same plant.
3 and 4 are the same plant. Some type of Yucca.
SOLVED: Unknown in Chiapas, Mexico
i think the first one is a species of Ilex (Holly) and the second one could be this Yucca although there is another that may be a better fit: http://davesgarden.com/guides/pf/go/734/
i was thinking also of this one, not a Yucca, but a Dracaena but i think my first choice is still Yucca g. http://davesgarden.com/guides/pf/showimage/356709/

The first one has Rosaceae fruit bottoms (sorta like rosehip) which puts it in the Rosaceae family which is why I suggested Photinia davidiana.
