For the last one:
For the second one:
The black balls follow the rule of diagonals going NE described above. The white balls follow a separate rule:
There are two white balls in every cell and they move in a counter-clockwise direction in the column they are in, as shown by the yellow balls above. If a white ball is at the same location as a black ball, only the black ball is shown.
The link provided by @Duck in the comments gives the answer to the first problem, so all three problems should now be answered.
