If you keep them in a line, there are 24 ways to line them up. Then of course there are squares, diamonds, rectangles, parallelograms, stacks, etc.

If all nine items are included in every arrangement, like 9 bookson a shelf with no spaces, then there are "9 factorial" =9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 = 362,880 different ways to line them up.
That would be 5x4x3x2x1 or 5! or 120 ways to arrange those objects in a line.
you can arrange 8 pictures 28 different ways
6! = 720
You can arrange and rearrange the word as many times as you like!There are 5040 different ways.
