Laws vary by country. In the US, they are not required to. In other countries, they might be.
Yes. Congears are required to have the same FMVSS121 compliant system which trucks and trailers must have.
Make sure spare tire is secured, if it has one. Make sure safety chains are secured to trailers and make sure converter doily air tank drain valve is closed
You're probably thinking of a B-train (known in other parts of the world as B doubles). It's a double trailer combination in which the lead trailer has a fifth wheel at the rear of it, to which the second trailer attached. Unlike A and C doubles, there is no converter dolly. B doubles can also be backed up without the risk of a converter dolly jackknifing.
