Same as person needing an ID for this plant. Bottom picture. Looks simular to a Agave grass like or there is a Sans w/grass like leaves. There are tiny teeth along the sides which is uncomon on Sans but I do have some showing this trait. Those points at the tips are also Agave traits, but I just can't say. The last one which looks more like Haworthia longiana, or Agave striata nana, or could it be S.t.~ ' Green Fountian'? others;
