To me, this one looks like Portulacaria afra. It's similar, but different from Crassula ovata.
Though the two species are closely related, they don't require the same cultivation.
That's why I always prefer to mention the scientific name (also) rather than just say "Jade tree". Not to mention "cypress" which can refer to many different species in vernacular American English, most of the time NOT cypress...
