Most of those plants are showing definite etiolation (stretched, weak growth) due to insufficient light.
#1 Looks like it might be a Gasteria X Aloe hybrid.
#2 Is likely Echeveria agavoides.
#3 Is an Aloe .... probably a hybrid. Could even be an intergeneric hybrid.
#4 Looks like a Senecio to me, but as Subrosa seems very confident, I willingly "bow out" before his identification.
#5 Is an EXTREMELY etiolated Echeveria.
#6 Appears to be an Agave.
#7 Believe this one is an Aloe.
#8 Is an EXTREMELY etiolated Haworthia .... Possibly Haworthia tessellata.
