[Star Wars] When Sith name themselves, they use words from their ancient language i.e. "Vader". Is the name "Kylo Ren" also a reference in this regard, or just something that was made up?

Kylo and Snoke are not Sith. Kylo is apparently the leader of an order called the Knights of Ren, who were the ones to wipe out the Jedi.

Where the name "Kylo" comes from is not known, it's probably just arbitrary.
