this is what i could put together, having just recently read everything after devil's reign + some info from the wiki @daresplaining
who knows matt is daredevil (post-purple children) - and when they find out (got most of these from the wiki)
foggy nelson - daredevil (2015) #1
luke cage - defenders (2017) #8
danny rand/iron fist - defenders (2017) #8
jessica jones - defenders (2017) #8
benjamin hochberg - daredevil (2019) #21
elektra - daredevil (2019) #24
wilson fisk/kingpin - devil's reign #4
peter parker/spider-man - daredevil (2022) #1
robert goldman - daredevil (2022) #1
(assuming a retcon, for plot reasons) apparently has known since they were in college together. but confirmed in this issue.
stick - daredevil (2022) #9
an undead puppet of the hand at the time. but since the hand says they use the mind/thoughts and body of the person they resurrect, i assume whoever gets zombied like this does remember what happened while they were undead, even if they are not in control of their actions.
sam chung/blindspot - daredevil (2022) #12
revealed here. seems to have known before the issue though, based on the way he addresses matt.
cole north? - daredevil (2023) #9?
he is present for the explanation matt gives to foggy about coming back from the dead. unless matt skipped a LOT of the story, and didnt explain HOW and WHY he died, cole probably finds out during this conversation.
jason - daredevil (2023) #10
confirmed here. finds the suit in #9
who knows matt's "death" was actually mike
foggy nelson - devil's reign: omega [A]
revealed here. actually learned between devil's reign #6 and this. always knew mike was posing as matt.
luke cage - devil's reign: omega [A]
danny rand/iron fist - devil's reign: omega [A]
jessica jones? - assuming luke told her immediately lol
elektra - devil's reign #6
always knew mike was posing as matt. learned mike's death in this issue.
peter parker/spider-man - daredevil (2022) #1
butch pharris - devil's reign #6
undone later? matt impersonates mike in (2022) #1 and seems to convince butch that actually matt is dead, mike is alive, and mike is daredevil.
who knows matt is alive after going to hell
foggy - daredevil (2023) #9
danny? - undead iron fist #2?
danny was alive when matt died, so he presumably knows he at least went missing, if not that he died or went to hell. danny dies in 2024, and daredevil (2023) ends in 2025. undead iron fist is released immediately after, and danny encounters daredevil. so presumably he knows matt is around.
elektra - daredevil (2023) #1
revealed here. learned sometime before the issue. has been spying on father matt for some time.
wilson fisk - daredevil (2023) #10
its unclear if he remembers anything greed made him say/know while he was possessed. but he makes references to matt's personal life, so presumably he knows at least while possessed. when they meet after fisk comes back, he does not address matt by name, which he has done in the past to taunt him. so. idk.
cole north - daredevil (2023) #9
jennifer walters/she-hulk - daredevil (2023) #5
its unclear if she remembers anything that happened while she was possessed by gluttony.
