Can we use different cell sizes for each block?

Answers:

You can make finer mesh using more cells for eg. (10 10 100) cells. But it is required to keep that for all blocks.
Different cells in each block will give an error due to discontinuity between cell numbers.

Can I use any arbitrary number of cells, say 28, as opposed to using a round number like 10 or 100?

Yes. We can use any arbitrary number for cells. But in some cases, like this pipe, we need to ensure that number of cells for connected blocks should be equal. Otherwise, due to continuity issues, we will get an error. So if we want to use (28 32 102) cells for one block, the other blocks should have the same number of cells.
