Catchy stuff!
Really hard to tell much from the photos, but yes, that is a Moroccan sa'if (nimcha) type sword with a bizarre harlequin looking material covering the scabbard. The koummya is most likely 'another koummya style dagger',
the broadsword is a hilt style known from Sierra Leone and West African regions that seems to have diffused east, the scabbard is as noted of Manding style work, and these usually had the familiar kaskara or takouba form DE blades.
Souk stuff, but certainly does look interesting for effect !
Best regards,
