Well, since you asked about the JLA up through the Satellite Era:
-Superman died in 1992 in the helpfully titled Death of Superman storyline.
-Batman has died like twenty-seven times, most notably in Final Crisis.
-I think Wonder Woman died at some point in the '90s, but I’m not sure when that was.
-Martian Manhunter also died in Final Crisis.
-Barry Allen died in Crisis on Infinite Earths, while Wally West died (and… sorta came back, or rather had it retconned out by time travel) in Tom King Hates You. I mean, Heroes in Crisis
-Hal Jordan turned evil in Emerald Twilight and died in The Final Night. I don’t recall any instances of any of the subsequent Earth Lanterns dying.
-Aquaman died sometime in the '90s too, but don’t ask me when, how, or what happened with the identity in the meantime.
-Green Arrow died… Guess when? The '90s. He was actually dead for a while. Connor Hawke took over and it was surprisingly pretty cool.
-I don’t believe Ray Palmer has ever been formally killed off, but if you’re hankering for an Atom death, I believe Al Pratt died sometime in the '80s, and Ryan Choi was unceremoniously killed off by the dumb Deathstroke-led “Villains for Hire” Titans.
-Hawkman… Man, who can frickin’ tell with Hawkman?
-Black Canary has not properly been killed off, thank goodness.
-Elongated Man died at the end of 52.
-Red Tornado has died like five hundred times because the writers can just rebuild him later.
-At least one of the Hawkgirls or Hawkwomen probably died at some point or something, I think.
-I don’t recall any Zatanna deaths.
-Ronnie Raymond definitely died in Identity Crisis. I’m pretty sure Martin Stein and Jason Rusch have both died at some point or other.
-I can never figure out whether Black Lightning was officially on the team. Some sources list him and some don’t. Regardless, he’s phased in and out of prominence due to rights issues, but I don’t think he’s died.
-Oh, and the Phantom Stranger is an honorary member, and it’s fairly clear that he can’t die.
