I want to add that Aloe variegata has been move to Gonialoe genus. A. variegata is now a synonym of G. variegata. https://en.wikipedia.org/wiki/Gonialoe_variegata

Bottom photo- Maybe a species of Aloe, possible A. variegata- Partrige Breast Aloe. Check it out and see if you have a match. https://www.smgrowers.com/products/plants/plantdisplay.asp?plant_id=3458

Middle photo- Maybe a species in the Calathea (?). If this is Calathea, flowers can help narrow down which species this is. Some of these include C. crotalifera, C. gymnocarpa, C. lutea, etc… The included link below is for C. lutea (Cigar calathea/Cuban cigar.) https://commons.wikimedia.org/wiki/File:Calathea_lutea_Cigar_2.jpg

Without their flowers to be certain, I suggest you check out these genera from these included links. Best wishes! Top photo- Maybe as species in the Kumara genus, possible the fan-aloe (K. plicalitis)(?). Click on images to enlarge from the included link below. When it blooms and you still don’t know, make new post with flowers photo. https://en.wikipedia.org/wiki/Kumara_plicatilis
