>>104829494I can't talk for certain about ALL the names, but I CAN confirm at least half of the names are actually real.
1º) "Chameleon": Confirmed and already debuted in Spain.
2º) "Weredad": Confirmed and it will air in Switzerland on 30th December. It is also the episode from where the clip of Marinette saying Cat Noir "I love you" comes.
3º) "Animaestro", "Bakerix", "Backwarder", "Silencer", "Onichan" and "Chris Master" have been confirmed as real episodes too. Along with "Chameleon" and "Weredad", they could be 8 episodes that have been confirmed to have been already dubbed in Spain.
4º) Jesus Barreda, voice actor of Adrien Agreste/Cat Noir is Spain, hinted about a new X-Mas episode. I would say that episode must be "Chris Master", because of the name: "Chris-Mas ter".
5º) "Bakerix": This must be an episode where a new character named Rolland debut, who lives in an old house and apparently is a "baker". It was reveleaded thanks to concept art from Alex Accorsi. You can find pictures in Miraculous Ladybug Wikia. Check some examples:

However, I would keep the possibility of being true just in case, because some names could be connected with confirmed spoilers.
