A few unknowns in my collection. Id’s please.

Hi everyone I have a few here that have either lost their tags or their current names are in question.
Any help would be great.... thank you all!

Don't know about #1... I want to say A. sobria, but that's just a guess.
#2 is definitely not ovatifolia. The mammilated margin, spoon shaped leaves would be typical of A. isthmensis or potatorum, but the compact size of the rosette makes me think the former.
#3 looks like the culitvar known as A. palmeri Kutsugen No Mai Ogi - a gorgeous pale blue leaved plant with lovely red and wicked spines (curved and distinctive)
#4 could be something like A. salmiana 'Crazy Horse' or the other similar cultivar 'Bothe' - with those extra wide leaves. 'Mr Ripple' is another wide leaved salmiana, but more green rather than the bluish plant shown.

No real idea on #1.

Agree on #2.

For #3, my first thought was also A. palmeri of some kind. Here's a couple shots of two typical A. palmeri I have, both similar size to yours:

For #4, my guess was 'Mr Ripple' too, and those do have a rough texture. Maybe just my experience, but I feel like 'Bothe' is notably thinner, on par with A. ovatifolia thinness, whereas I find 'Mr. Ripple' much closer to it's purported proto-americana parent in that regard.

Here's my 'Mr. Ripple', to illustrate just how green I mean it is compared to the others mentioned which are more blue

Thanks guys, the first agave is still quite small see what happen as it grows on.
Third agave I had suspected palmeri but wasn’t sure.
The last one could be ‘crazy horse’ but havent heard of that available in Australia yet. I don’t thing it’s ‘Mr Ripple’ as ive go this one in the garden.

That last one does resemble the unique A. ovatifolia 'Vanzie' with the twisty leaves.

^ But not the marginal spine teats.

1. Could be salmiana
2. A. isthmensis
3. Spination's guess is a good one, I would go with it
4. A. 'Mr. Ripple'

Perhaps #1 is a form of Agave asperrima, given:
1) thickness of the leaf near the base;
2) downward curving teeth;
3) dark leaf margins trailing an appreciable distance from the terminal spine;
4) bluish leaf banding.

In fact, it has a remarkable resemblance to several short-leaved Agave asperrima that I grew from a batch of seed from Baluarte, Mexico (offered by Mesa Garden some years ago).
