Hello, I was wondering if you could ID these! Tall lad in the back Ive had for a while but the other four are newbies :’) I think the brown-green one is a type of sedeveria but Im not quite sure… thanks in advance!

********************

Clockwise from the tall lad in the back:

1. gasteraloe

2. acanthocereus tetragonus

3. sedeveria (looks like lilac mist), but might also be a pachyveria

4. echeveria shaviana

5. echeveria blue frills

(The last two are tentative IDs… it’s hard to ID ruffled echeverias when they’re not at their best.)
