It is! Thank you From Wikipedia "a forest cactus, growing as epiphytes at elevations between 0 and 1850 meters in Brazil". Cactus family, I thought it is a desert plant:(
I think number 1 might be Browallia, maybe Browallia speciosa, common names amethyst flower and sapphire flower. There are several cultivars. I don't understand the naming of some I'm seeing called Browallia speciosa major and then a cultivar name. Solanaceae.
Liable to be a botanical designation for horticultural forms with built-up parts, perhaps not actually completely airtight if used only for garden varieties - with there being no wild plants with the same features.
