Can anyone identify these Agaves

They are in the wild. High elevation Guatemala.
I have the list of Guatemalan native species. Below:
Agave americana subsp. americana
Agave chiapensis
Agave fourcroydes
Agave ghiesbreghtii
Agave hiemiflora
Agave hurteri
Agave lagunae
Agave pachycentra
Agave seemanniana
Agave sisalana
Agave tecta
Agave thomasiae
Agave vivipara var. letonae
Agave vivipara var. nivea
Agave vivipara var. vivipara

But I'm struggling to identify these.
The first 3 may well all be the same species: Click to enlarge. I can upload larger pictures if nessesary.








Your help is appreciated!

Regards,
Phil

 

The last one looks like Agave sisalana.

 

Yes! Agave sisalana is the only one with long leaves. But i wanted to check it.

 

Wow..I saw Agaves like these ,too when I was in Guatemala.Didn't get a chance to take pictures though.

 

The first one looks like Seemanniana to me, the 2nd looks similar but hard to see the 3rd pic.
