Sorry, Patusho, without flowers the last 3 may be almost impossible to ID beyond genus.
I don't recognize the first one either, except that it appears to be an Aechmea in the subgenus Platyaechmea. That's a pretty big group though, and it doesn't match anything on FCBS. The closest seems to be A. retusa, but I don't think that's it. If you email that photo to the Bromeliad Identification Center along with information about the locale you might get an answer.
