Pic 1, cotyledon or crassula?, the leaves don't get a reddish edge, and I have never seen it flower.
Pic 2, not sure, some of the leaves don't "open" and look tubular .
Pic 3 not sure on this one either, any help appreciated, thanks in advance.
Thankyou for the answers, I agree number 1 is Cotyledon Orbiculata, number 2 is definitely not Kalanchoe Blossfeldiana, you can see the flower growing out to the left, it is a palish white/pink and very sparse, this is also an old plant, it is not a new cultivar.
Still searching, these plants will be the death of me, trying to name them.
