Warriors Three
In 2011, Kevin Feige says that there could be a Thor spin-off of The Warriors Three.

The Winter Soldier
Captain America: The First Avenger director Joe Johnston has expressed interest in doing a Bucky solo film, quoted as saying "I told the Marvel guys that there is a character that I’m really interested in called ‘The Winter Soldier’ and that if, ‘you guys decide to make that picture I would definitely be interested.’ […] I just think that it would be interesting to take a character that was in ‘Captain America’ and build a story around him. Plus, I like Sebastian Stan a lot (who played Bucky) I think he would be an interesting actor to build another feature around." While no official word has been given, Johnston said that the film most likely won't happen until after Captain America 2, and has expressed interest in working with Scarlett Johansson and crossing over with her character of the Black Widow. In the comics, Bucky and Black Widow have a romantic history dating back to the Cold War, and though Black Widow appeared in Iron Man 2, and the Cold War conflict was alluded to with Whiplash's treacherous father Anton Vanko, they did not develop any relationship between the Black Widow and the Soviets, leaving the possibility for it to be expanded, whether in a Winter Soldier or a Black Widow Though the film is only in the planning stages and has yet to start development, Sebastian Stan is signed on to reprise his role in a total of 6 Marvel films .Both Johnston and Stan have said that they're ready to get on board whenever Marvel is, and that it is something they're both anticipating.

War Machine
Kevin Fiege says that this movie will most likely happen, but not for a while.

Black Widow

Hawkeye

S.H.I.E.L.D.
A S.H.I.E.L.D. movie was alluded to by Samuel L. Jackson in a recent interview where he stated it is the next movie that Marvel is planning after The Avengers. It is not to be confused with the Nick Fury spin-off movie.

Nick Fury
Andrew W. Marlowe was hired to write the script in 2006. The script he wrote was loosely based on Jim Starenko's Nick Fury: Agent of S.H.I.E.L.D. series and involved the S.H.I.E.L.D Helicarrier. The script was not written for the version of the character appearing in the Marvel Cinematic Universe as it was constructed before Samuel L. Jackson was cast but Marlowe said that the script could be "tweaked" for Jackson's portrayal.

The Avengers 2
In October 2011, producer Kevin Feige hinted at a sequel to The Avengers during the New York Comic Con stating, "Iron Man 3 will be the first of what we sort of refer to as phase two of this saga that will culminate, God willing, in Avengers 2". In March 2012, Joss Whedon stated that he would want a sequel to be "...smaller. More personal. More painful. By being the next thing that should happen to these characters, and not just a rehash of what seemed to work the first time. By having a theme that is completely fresh and organic to itself."
