Are these Gundam manga's canon?

Mobile Suit Gundam: Blue Destiny
Mobile Suit Gundam: The Lost War Chronicles
Mobile Suit Gundam: Ecole Du Ciel
Mobile Suit Gundam: The Last Outpost
Mobile Suit Gundam Seed: Astray
Mobile Suit Gundam Seed: X Astray

If they are not canon, why?

The issue of what's canon or not can be quite confusing... It'd be better if you refer to this thread instead.

[J-Lead]

To sum it up, the only official works you've listed are the Astrays as far as I know. The only things that make it to official status are animated features and a select few works that bear the official stamp of Sunrise (Astray, in this case.)

It should be noted that the Blue Destiny manga was praised for being so close to official materials, so it wound up being the most 'official of the unofficial' works.

Ecole du ciel provided us with a name for the pilot of the MS-06Z Psycommu Zaku http://www.mahq.net/mecha/gundam/msv/ms-06z.htm

And aprearantly whoever wrote that profiel thinks it to be credible.
So prehaps it is canon in the sence it doesn't conflict with anything.

Please don't use MAHQ as evidence for what's canon/official. We have profiles for all sorts of video games, manga and novels that Sunrise classifies into various levels of official/non-official. Since the subject has already been debated in extensive detail in the thread linked above, there's no reason to keep this redundant one open.
