Look like Sempervivum to me, but I could be wrong. Your media, btw, looks far too organic (which would lead to it staying too wet too long and possibly leading to rot).

I would guess Sempervivums too; but poor guys are suffering...different potting mix + drainage holes in containers and growing the outdoors (year round) in good sunlight should help.

However, if you move them to full sun outside do it gradually. Plants can sunburn.
