I'm missing something.

5th Dimension contain all possible timelines that lead to one END OF UNIVERSE.

6th Dimension contains all possible timelines to all possible ENDS OF UNIVERSE.

8th Dimension contains all possible starting conditions that lead to one BLANK.

9th Dimension contains all possible starting conditions that lead to all possible BLANK.

What is it that the 9th Dimension actually contains? To contain something you need two conditions. For the 6th is was from one possible starting condition to that starting condition's possible ends. For the 9th the first is all starting conditions but the second... I don't know what it would be. Is it possible that truly the 9th Dimension is where it ends and not the 10th?
