Rita starts by splitting the contestants into 32 five-member groups. That means at least eight sentai's worth of members were completely eliminated before even appearing in this battle, since this battle clearly shows sixth and extra rangers.
The telegram was translated thanks to a language code from DekaRanger ( https://twitter.com/tavion_jackson/status/1096981647034077184 )
RyusoulBlack uses a Tsuyosoul. The name in Japanese basically means "Looks strong/tsuyo-sou". Sou/yes becomes soul, etc.

Rita and Planet Nemesis are references to ZyuRanger. Rita is the dub name for Bandora when it was adapted to Power Rangers. Planet Nemesis was where Bandora was sealed.
Stinger is still wearing his commander jacket from the end of KyuuRanger.
Yamato shows that he's met Marvelous before. That's because the Gokaigers returned for the 40th anniversary of Sentai in episodes 28-29 of Jyuohger.
At one point, KirinRanger uses the drunken fist, which was something he did in one episode.
BoukenYellow is one the monstrous strength team. Her catchphrase was that she was "The Strong Adventurer".
BoukenSilver relaxes by eating a celery. Then he makes Sousuke eat a tomato. In Boukenger, eating vegetables was his character trait.
Sousuke and Eiji are both on the Vehicle Team. Sousuke's partner is a living car named Speedor, whom he tries to summon. Eiji was on Boukenger which was a vehicle themed sentai. When defeated, Sousuke says a modified version of the Go-Onger team catchphrase. Eiji talks about adventures and Precious, which was the McGuffin for Boukenger.
