1st is Austrocylindroputia subulata...

Whatever they are, I suggest you remove the fibrous topping as it will promote rot around any cactus or succulent plant you have. What soil mix are they growing in please? Can't see it well, looks dark and peaty which =water retaining. All c/s need fast draining mixes and minimal watering. Plenty of recipes can be found using the search box at the top. Half c/s mix and perlite is easiest.

#2 looks like a sempervivum, if so, it's best suited to outdoor culture, no doubt someone will confirm my tentative ID!

Thanks a lot Gill for your recomendations, I will change the soil for a more suited one, I just purchase them, and I have been spraying them with little water. Aparently the second one is a sempervivum montanum.

Spraying succulents isn't such great idea...they need to be watered when potting mix is almost dry, thoroughly. Then they should be left alone until mix dries up again. Watering in 'sips' or spraying is not for succulents.

Sempervivums are hardy, Alpine plants. Should be grown outdoors year round, in containers or in ground. They do not need 'rich' soil, should be in well draining mix just as any succulents.
