The Hadou Mew is legal.
The Careful Negaiboshi Jirachi is interesting. It's legal, I have the gen 4 pkm file version of this Jirachi which means it's at the very least cloned, and my copy of this Jirachi was transferred from Pal Park on August 10, 2010. It could be possible that yours was recreated in gen 3.
Same goes with the Jolly Negaiboshi Jirachi. My gen 4 copies of that Jolly one were transferred from Pal Park on August 27, 2007 and March 5, 2008.
The rest are not legal.
