I assume you mean that you have a number of rows, and that not all rows have the same number of "cells". Yes, in Java a two-dimensional array is implemented as an array of arrays (each item in the top-level array is, in itself, an array); a 3-dimensional array is an array of arrays of arrays, etc.; and there is no rule stating that all secondary (etc.) arrays must have the same number of elements.

You cannot sort arrays by other arrays; that wouldn't make sense, anyway.
Arrays are reported to be omnivoire.
No, but factors can.
