It is Kalanchoe delagoensis. Many consider these weeds. I happen to like them (but you have to be vigilant about picking up the baby plantlets that fall from the leaf edges (starting new plants). This one may not look good right now, but it is a survivor. It can grow in just about ANY conditions...including from a crack in the cement, a piece of your carpet, an empty pot, etc. :D You have been warned. The flowers are very pretty. :) I take it back...if you have SNOW or freezing temps...it would probably not survive that. Anything else...it's A-Ok.

The fuzzy leaves make the ID a bit easier, for me at least. My guess would be Echeveria pulvinata, though Echeveria setosa also has fuzzy leaves. There is an Echeveria 'Doris Taylor' that is a hybrid of the 2 if I remember correctly. As with most Echeverias they like full sun, but must be acclimatized to it. "Fuzzy" Echeveria are reported to be more cold hardy than the other species and said to withstand temperatures down to around 25F (though I've never personally tested this) Still think it might be getting too much water. Your watering frequency seems correct but it still looks overwatered, making me think that the soil isn't drying out fast enough. I only say this because the lower leaves look a bit translucent which I think is caused by excess water, kind of like edema. Could try changing it to a faster draining soil (repot it with more pumice or perlite) and see if that helps, or reduce watering a bit to like once a week or every 10 days.. just don't let the roots dry out too much or they may have problems. Hopefully someone else will weigh in on this, I'm still a novice when it comes to succulents.

Did you mention where you live? (Good idea is to put general location and/or growing zone next to your name...) Yes, Sempervivums could be grown indoors but usually they don't look their best. I am not sure if they are better off with having to spend winter outside (some plants have to have x number of cold days to grow well); unless you get them really good light during winter they usually look quite sad. During summer it may not make that much difference. But amount of light is always less indoors than outdoors. But if you don't have access to garden or deck-balcony, you have to just do it indoors. Many ppl have to, living in apartments without balcony or any other outdoor space. All of the succulents need lots of light otherwise they stretch as I already mentioned about Painted lady. I use lots of supplemental lighting in winter, and probably will improve even more next winter. here is same Echeveria purpusorum, still indoors (March) and blooming, under lights: Adding more perlite definitely helps.

Tallest one (in your hand) is Crassula mesembryanthemoides; one next to it may be a hardy succulent/ground cover Sedum reflexum (Blue spruce sedum) - not 100% sure; one on very left below Crassula is Kalanchoe tubiflora (Bryophyllum tubiflorum); very bottom center, I think it may be another hardy groundcover Sedum rupestre 'Angelina' . The large center one and smaller to it's right - I am not sure. Looks like there are 2 more hiding (maybe 1 is an offspring of the big one?), but can't tell what they are from the photo. They all need fast draining potting mix, needs to be potted in container with drainage holes or ground - depends what your climate is (hardy sedums will overwinter in cold zones as low as z4 or even z3). And good sunlight. Kalanchoe tubiflora will self-propagate, every little plantlet you see on the leaves is potential plant - they just fall off and grow...in some places they are considered 'invasive'. When posting multiple plants for ID, it is easier to refer to plants if they are numbered. Could you add the general location and/or zone to your name?
