The last time all five were together was in the Gokaiger - Goseiger - Super Sentai: 199 Hero Great Battle film, which made its premiere back in June 11, 2011. As to what happened to the angels after the series ended, Mikiho Niwa (Moune/Gosei Yellow) and Rika Satou (Eri/Gosei Pink) got married to their partners. More info about the rest of the cast in this post I made back in 2016 to commemorate the 5th anniversary of the show's last episode.
