NEXT MOVIES AFTER AVENGERS END GAME
Spider-Man: Far From Home
According to different rumors, in this film we could see a Peter Parker affected by the death of Tony Stark, however, we will have to wait until Avengers Endgame to get out of doubt.Here below I will let you the teaser in which you will see the new enemy of Spiderman and other characters that we saw in the last movie.
Black Widow

The director of the MCU has confirmed a separate film of black widow and in this film we will know the story of Natasha Romanoff before joining the Avengers, so everything will unfold years before Endgame.This new movie will be available by 2020.Personally,I hope to watch who will interpret the young character of Romanoff although there are rumors that will be Emma Watson.
Black Panther 2
As you know Black Panther was a successful movie in 2018 for that reason the new of a sequel was well recieved.This movie will be released in 2021, and obviously is on the timeline after Endgame. This means that Black Panther will return from the death he had in Infinity War.

Doctor Strange 2

Like Black Panther, Doctor Strange will return from the dead, as his second film will be released in 2021, and will also be in a timeline after the events of Endgame.
