The first one might be an Echeveria, not sure about the exact species though. A common one, I think, but as i_like_pi pointed above, the plant desperately needs more light. Try to move it gradually towards light source, bright windows or add grow light. Also, try posting it in the cacti & succulents forum for more specific ID and care advice. Good luck!

The Jade looks like Crassula arborescens (vs. C. ovata for regular Jade.)

First one looks a bit like kalanchoe 'Flapjack'.

Assuming one is referring to Kalanchoe luciae or thyrsiflora by flapjack, I disagree because both of the plants pictured above have much smaller leaves. Flapjack isn't a cultivar, just a common name, so needn't be punctuated as one (capitalized & enclosed by apostrophes.)

Compare the Echeveria to 'Perle Von Nurnberg,' often seen in BBSs the past few yrs.
