In the IB Example, I am getting multiple solution for the Maximum Arrow Sudoku. Am I missing any rule/constraint here. The 2 and 6 in R1 and R9 are interchangeable.

R5C5 = 6 with a circle. If you swap the 2s and 6s in R1 and R9, that arrow with '6' won't be satisfied.

Why cant I have a 6 in R1C9? How does it negate the condition?

R1C9 must be '6', as in the solution.
If you swap R1C7 and R1C9, and corresponding R9C7 and R9C9, the arrow starting at R5C5 with a '6' would have digits 3, 3, 5, 2 along its arrow, and hence, does not satisfy the 'maximum' rule.

If its still not clear, it would help if you could share your solution which doesn't match the one in the IB.

Rhombus Sudoku
Is it necessary that there will be 9 rhombus and that each rhombus will have 9 different numbers in the middle ?

No.
That is just the theme of the IB example :-)
