Here's my list.
Kuririn
Kienzan- This varition as far as I know appeared only in the anime (correct me if I'm wrong
Majin Buu (Good)
Hurricane Dash- Buu dashes through the entire city leaving a trail of ki behind him destroying everything in his path. While was given a name in the video games (Budokai and Super) it was never acknowledged by any official sources (manga, daiszenshuu, ect).
Majin Buu (Junsui)
Absorption Kikoha- Another attack that appears only in the anime, It first made it's debut when Buu two times first when fighting Yamucha and Kuririn in the Afterlife and lastly against the Super Saiyan 2 Goku. While generic in appearance it has little quirk to it as it’s able to absorbs incoming ki blasts and increase in power.
#18
Electric Wave- This attack also appeared in a filler scene, after a confrontation with a biker she gets angry and shoots electricity to the ground scaring the biker gang away.
#17
Water Blast- While Piccolo and 17 fought underwater, 17 powered shot a massive water-based attack at Piccolo.
Kishime
Electric Whip- While Ebifurya and Misokatsun attacks were given names, Kishime was left to dry. He spouts gel-like whips from his body that conducts electricity.
Neiz
Electric Blast- Niez charges electricity in his hands fires it at Piccolo. It not only shocks him put seeming stuns add to that it's seems long lasting.
#14 and #15
Kikoha Combined-14 and 15 combined their energy into giant ball of energy.
