This doesn't seem to be a problem.

This could be a serious problem. What's the current Debian stance on
IDEA? Can it go in non-US/main, or just non-US/non-free?

Well, it's unclear what IBM thinks about this algorithm, so the status
here is unclear.

No problems here.

This is the same as the other MARS one, I think. They are talking
about the same algorithm, right?

Well, the two major questions are IDEA and MARS. I'm sure people have
already made a decision about IDEA, but Ihave no idea about MARS. I
would think it would have patent-unencumbered since it was submitted
as an AES candidate, but since it didn't win, I'm not sure what the
status is.
