Burkhart, a german mineral dealer specializing exclusively in Moroccan minerals and a Tucson regular at
the InnSuites, told me he had those specimens analyzed and it was indeed Devilline overlain by Gypsum.
It makes sense - a sulphate overlain by a sulphate. John S.

Yanick papagoite, shattuckite, ajoite are not known so far. If you have any analyzes I will be happy to take a look. They are known from South Africa.
Cheers!

I created separate topic on this problem (http://www.mindat.org/mesg-7-278255.html), because there is no reliable information on identity of above mentioned green crystals (rosasite or devilline?). I tried to do simple test on the specimen from my collection using HCl. Gypsum was dissolved with effervescence, but green crystals remained intact. So, they are not rosasite. I'm not sure about solubility of devilline in HCl, but it seems to me that it is insoluble. So, we probably have devilline in these samples.
Best regards,
Dmitry.
