Spitz,
You have no idea how much you are asking. It is very hard to ID.
The last one which looks more like Haworthia longiana, or Agave striata nana, or could it be S.t.~ ' Green Fountian'? others;
S. Ballyis, S. Gracilis, S. Patens, S.Pinguicula, S. suffruticosa, and/or S. Francisii.
I know it is impossible to correctly name Sansevieria. Even the experts get into arguments. This is only best guess and nothing more. Also you can not use a name unless you are absolutely sure of it. This can not be determined here and with only a picture. I know this is not much help. I post this on my Sansevieria group. Should get some more responces.
