Interstellar: 5th Dimension Explained

One thing that is left totally unexplained in the movie is the 5th Dimension. It talks of 5th Dimensional beings. It establishes Time as the 4th Dimension. But never lets out what the 5th Dimension is. It is just told that Future humans might have become 5-Dimensional beings.
1. Who are 5th Dimensional beings?
By referring 5-Dimensional beings, Nolan refers to beings for whom manipulating 4th-D (Time) is a piece of cake. They are beings who are no longer bound by the rules of 4D. They are not able to interact directly with the 3D people. They can only interact with people in 3D/4D, by manipulating gravity, which is explained as force that transcends dimensions.
2. Why has 5th Dimension not been explained in the movie?
Nolan has used 5D as a reference to people who have moved beyond 4D. Who can move across multiple 4D’s (Just like 3D people can move across multiple planes i.e. multiple 2D’s). Something like super humans. I think Nolan might not have wanted to over complicate already complicated fundas. Hence he just left at 5D beings who can manipulate 4D.
3. What is 5th Dimension?
My take is Parallel Timelines. In 5D we can’t just move back and forth in Time (Single line), but also adjacently (adding one more dimension). It means that 5th Dimension adds parallel timelines. In 5D we not just move through past-present-future but also different timelines of each moment of past-present-future. In Tesseract 5D humans, either rendered 3D projection of just one of the parallel timelines or there were all the timelines there, but Cooper concentrated only on one.
4. Why can’t 5D humans interact with 3D humans directly. Why toy with them indirectly?
Maybe they can. Maybe they can’t. Maybe they just choose not to interact directly. Just like StarTrek into Darkness’s opening sequence, where only observations of other evolving planets was allowed, but interference was outlawed. Or as Nolan explained, beings from different dimensions can only interact via manipulating Gravity. As Gravity is the only thing that transcends dimensions.
