I know few of the instances: Spock was resurrected in the Star Trek: Search For Spock movie. Kirk was resurrected in the Star Trek Into Darkness movie. Most recently, in S02E05 of the Star Trek: Discovery TV series,
Dr. Culber was resurrected.
How many people have been resurrected from complete death in the entire history of Star Trek?
I want to clarify here that death here means ordinary brain death situation. Timeline and Q related ju-jus aren't allowed. Plain simple cloning in which memory of original host doesn't survive won't be called resurrection either.
