6. Momoshiki Ōtsutsuki
Momoshiki Ōtsutsuki is an ex Ōtsutsuki clan member. He has multiple Kekkei Genkai Abilities as well. First he has Byakugan in his eyes, giving him the ability to have 360° vision. Also, he has Rinnegan in his both hands allowing him to absorb all ninjutsu. In addition to these two Kekkei Genkai, Momoshiki Ōtsutsuki also has Wood Release, Ice Release, and Lava Release Kekkei Genkai as well. This makes a total of 5 Kekkei Genkai for him.
5. Kabuto Yakushi
Kabuto Yakushi was a disciple of Orochimaru himself. Kabuto has a total of three Kekkei Genkai which are, Jūgo Clan’s Kekkei Genkai, Sakon and Ukon’s Kekkei Genkai, and Shikotsumyaku. He stole all these Kekkei Genkai back in Naruto. However, I’m pretty sure that he still has access to all these techniques.
