Starting with your second pic:
#1 - agave of some sort
#2 - aeonium, possibly 'Sunburst'
#3 - cristate or mostrose form of some type of cactus, I've seen it before, but can't remember the name. I think it's somewhat common, so one of our cacti/succulent experts should probably easily know it
#4 - maybe another aridity of aeonium but not certain
#5 - Kalanchoe tomentosa, I believe
#6 - Croton variety, probably 'Mammy'
