I should mention on number 4, there are 2 different things in that planter. Ignore the thicker stems. :)

Hi,

Those pots seem a tad large for those cuttings. Am hoping they have drainage holes, but the lack of saucer underneath suggests not. That will be a problem, either sooner or later.

The 1st looks like a Peperomia (maybe obtusifolia).

The 2nd some kind of succulent (needs a faster draining mix, that mix looks too rich), maybe a Crassula.

The 3rd needs more pix pls. could be at least 3 diff plants I can think of (Hoya, Columnea, or forgot the other)

The 4th I don't recognize.

Thank you. I believe they're all some kind of succulent or similar type plant. All of them have thick rubbery leaves and fleshy stems. The only exception is the 4th one, which seems quite delicate at this stage, though it's leaves are still thick and fleshy for their size.

Everything has good drainage holes. I water in the sink, drip dry on a towel for a while and then don't worry about damp sils much after that since they're marble.

Other than the 1st, I think I need to see pix of the mother plants, if you're able to supply them. :)

I agree, Peperomia obtusifolia for the 1st.
Does the 2nd have opposite or alternate leaves?
Third, could be a Nematanthus (Goldfish Plant).
4th, possibly Sedum sarmentosum (still, would like to see pic of mother plant).

The second one has opposite leaves.

I definitely agree with the Peperomia for the 1st picture.

I can get pictures of the mother plants, but I'm not sure how helpful they would be. They clearly don't get enough sun or adequate watering so they're all leggy, bare and lopsided.
