In the MCU series Agents of S.H.I.E.L.D., we learn of the resurrection of S.H.I.E.L.D. agent Phil Coulson through the T.A.H.I.T.I. process. In the background of the scene in which this occurs, there are a few people. The MCU Wikia page says that Nick Fury is supposedly there, but I can't really tell. Is there any source that says who these people are?
