The cactus I have a feeling are Chamaelobivia. Now what species your gonna have to wait till it blooms:). Could be a Chamacereus Peanut Cactus, but like I said blooms will give you the true id. The second one is an Echeveria. Maybe E. 'Chroma' not 100% sure with that id tho:). They both need more light. Acclimate slowly or they could burn:).

If the blooms look like this then you've got a Chamacereus aka Peanut cactus:).

If the blooms are more fuchsia then you have a Chamaelobivia 'Rose Quartz'. These two are the most common, but if you get white or yellow flowers then you've got a different species/hybrid. Hope that helps:).

@Kara 9b SF Bay Area CA thank you so much! Do you know the steps to acclimate plants to sunlight? If so please let me know! I've looked it up but I'm too scared to try it because I don't want my plants to burn. It's 95+ degrees where I live right now and the sun is very intense! Could you please give me some tips?(:

I would start off with morning sun:). At about 11am the plants should move into some shade. I'm not saying everyday at 11am go outside and move the plants into some shade, but put somewhere outside where the sun shines until about 11am or even till 12pm then the plants get shaded. The afternoon sun is usually what burns the plants. Unless you live on the equator and even then morning sun could burn plants;).

Do this for a week or two. I have a feeling full morning sun will be enough for the echies, but that cactus can take all day sun. The two above get all day sun:). So after about about one or two weeks of morning sun move the plants into more sun. A spot where shade comes at like 1pm/2pm. Do that for a week. Then move to a spot where the shade comes at about 3pm. Do that for a week or so. If you get no burns at the 3pm mark, they're ready for the all day sun:). Does that make sense. It's kinda hard to explain.

Your mix looks fine so your good there:).

Thank you so much!!!
