Unfortunately, in none of the photographs all characters are visible that are important for identification. Especially, the tails are missing in all specimens/photographs.
I agree with Will, the first image is H. granulata, you can see from the snout shape and white flecks on the dorsal surface. The last image is D. microps based on the size of pelvic fins and broad fin base.
For first species, I agree with Dr. White and [Fahmi] Fahmi. I found same specimen in the Oman Sea (with white flecks and thorns on the dorsal surface) (attached file), but important note for me is missing the tails in both specimens and other previous report.
Hi Alireza, That image you attached looks like it is Urogymnus asperrimus. Has no tail spines and thorns over all of disc. closely related to H. granulata and should be in same genus
