Well, if we're going by Skyrim measurements, he could potentially make up to three full suits of Glass Armor (Leather is the only thing not found in the chest but shouldn't be too hard to get) and up to 40 Glass Swords (Again, Malakaus would need to find the leather). But if we're going for Realistic, it'll probably take Malakaus at least 10 ingots alone just to make the chest plate and twice the amount of moon stone, so maybe only one full set of Glass Armor with perhaps enough for a sword and dagger if Malakaus doesn't make a shield. If it's just weapons, than only about twenty or so swords since it would take at least two Malachite Ingots with a Moonstone finish. So he could use the contents of the chest to make one full suit of glass, or arm ten or so of the crewmen with Glass Swords. Though he'll more likely create the weapons for the officers and his Typhoon Warriors, which likely means that he'll use more materials to make Harasha a Glass Warhammer, which would cost him more materials.
