That little fuzzy plant
"Don't know what is this, the leaves doesn't look like succulent, but it was sold with other caudex plants"
I think it reads Rechsteineria. Perhaps Rechsteineria leucotricha. ( Sinningia leucotricha ) If so, that one is an absolutely adorable caudiciform (when older) with very pretty red blooms. I am thinking this one! "Brazilian Edelweiss"
