Nezirangers, D and Enter should be added in this category?
Is sure to add these guys in the section Died again after resurrection? because...
Enter revived in Kyoryuger vs. Go-Busters then he died again during the battle.
D revived in one episode of the series but withouts his Deathryuger powers (except his weapon) however he had a ranger mode before his first death and he is classified as a deaceased sentai ranger.
The Nezirangers were revived but pressumably killed again when their cards were destroyed.
