Can someone please enlighten me on all 5 dimensions of reality?

I have a very basic understanding of the 5 dimensions to say the least. I know that 1 dimension is a straight line, 2 dimensions is a square, 3 dimensions is a cube, and the 4th and 5th dimensions are more complex figures that are mostly beyond my understanding. We supposedly live in a 4 dimensional universe, composed of the 3 spatial dimensions and time. I understand that much. Does this mean that any universe below the 4th dimension is without time? Would a 3D universe be similar to ours but unchaining (everything is still)? Also someone please explain to me what existing in a 1D universe would be like, also what a 5D universe is and what it would be like.
