So I had seen the Daredevil Season 2 and I had caught up with bunch of Major Easter eggs, References and Spoiler Alert
The First I had saw is the Dogs of Hell which we had already seen in Agents of S.H.I.E.L.D.
The another which I had caught up with is Stark Tower in Episode 5 at 24:42 you just had to pause the video watch the image below.
The other one of Jessica Jones there are many Jessica Jones references but this is one of them watch the video from 30:00 to 31:30
And the last one you can see in last episode, watch that hulk kind of figure but I am sure its HULK and the battle of NY scene from Avengers movie.
