It could be x Gasteraloe "Flow"

#1 Very difficult for me to tell but looks like an Echeveria there are millions of them making it difficult for me to tell as I only have one small Echerveria in my collection of succulents If someone ID's it as something related to it cross breeding wise they'd more than likely be right ,I would humbly bow in there direction. #5 Some from of cacti... What type? As it is in pic, it's seen in a particularly odd form of growing. I think it's Hatiora salicornuoides An Epic type cacti and would be very close to the same /exact as any holiday cacti in cultivating. Normally the foliage look like beer bottles. Yours has air roots this one, air roots are sometimes normal yet air roots are not desired if your out to seek a ribbon It also indicates a lighting problem by the foliage shapes. Lighting and soil is a concern that you need to address. IMO as you read from others they don't speak from grandiosity or a superiority complex they/some speak with experience and in concern for yours and your plants success. As soil is one topic as is lighting being Lutheran each area of concern is yours to adventure, or ask about, or research.

a Haworthia, could be H limifolia, or hybrids, or related species, but not Aloe
