Just wild guesses on my part ... I'm really not good at trying to compare photo's, but those I've given names for reminded me of plants in my collection.

When I went to the nursery that day I discovered that the memory on my camera was almost full. I normally take 3 or more of each plant but only took one of this. I've looked at pictures on other sites and think you are correct.

No. 1 photo does look like a portulacaria afra or elephant bush that has been grown in part shade that's why the branches/stem are not too burgundy looking and N0. 5 photo does look like Euphorbia Tirucalli
