For a proper determination you need good sections, peels and thin sections, even if you want to be clear (roughly spoken) on genus level. Perforation and ornamentation of coralline septa, pali, synapticles, columnella and endotheca are not identifiable on this "out of the field"-Picture.
Another problem with determination might be, that a lot of mesozoic coral species and genera are very often on a bad valid taxonomic status.
Additionally, some more information about the site and stratigraphical setting your finds are from could be helpful.
Best regards.

Thank you Johannes K. for your answers. Yes like the Jurassic corals of Morocco, corals have not been revised since Beauvais 71 or 72 work's!. The two pictures come from Bajocian deposits!
Hello Ait Addi,
you may contact Dr. H. Löser
http://www.geologia.unam.mx/igl/index.php/loeser-h/465-loeser-hannes
He is a well known specialist for mesozoic corals, so maybe he can help you, if nobody else do it here.
Best regards
Johannes
Thank you, Johannes K. for help. Ok I will contact Dr Löser H. for any ideas about Bajocian corals!
Kind regards

The upper photographs are definitely solitary corals.
The lower one could be a trace fossil! It reminds me of Hillichnus Bromley et al. However, high resolution pictures and more specimens are necessary to confirm their identity --Fossilized foliage, probably a fern OR trace fossil.
Yes, could well be Montlivaltia. The lower fossils seems to be a twig form an araucarian conifer
Thank you dear colleagues for your help to recognize these fossils. The lower picture is not trace fossil! It could be a fern? or a twig form an araucarian conifer? as it suggested by Meyer Ch. A.
All the best
Ait Addi A.
At first glance, it seems the impression of a fern frond terminal.
You need to look more plant impressions in this outcrop.
You have to examine very closely whether these veins exist in its pinnulae.
Greetings
The lower fossil is a conifer shoot. Conifer foliage is fairly conservative so placement will be difficult. Higher resolution photos are needed to see if more detail is preserved. More specimens would also help.
The first figure is the coral Montlivaltia (Coelenterata) while the second is an impression of pinnate leaf of angiosperm.
