1 is an agave probably Agave parryi or harvardiana, but hopefully someone who knows something will come tell us 2 looks like some kind of Faucaria. Again, someone who knows things...?

Hi, I'm new to the forum. Can someone please help me identify what Family, Genus, and Species of cacti/succulents I have growing? I have uploaded pictures of each of my plants. If my plants have a nickname could you please give me that info also?

Gymnocalycium is the genus, but as far as species I don't know.

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:).
