Based on the single photos, here is my guess
1. Ottoman style horse pistol. One of many thousands produced with local and imported parts. Likely assembled at one of the many small gun shops in the Balkans during the early-mid 1800's. These pistols were popular through out much of the Ottoman Empire.
2. This is what collectors commonly refer to as an Ottoman knee pistol/blunderbuss. Again, likely made at one of the many gun shops through out the Balkans. Very popular in these Eastern markets, but never caught on in the West. Also early to mid 1800's.
3. A pocket or belt pistol with a Roman style miquelet lock. Likely from Naples/Central Italy, early 1800's. Many of these smaller, more concealable pistols were carried for personal protection.
4. A European powder flask. Could be from almost anywhere.
5. The longer blade looks like a European hunting type sword. The other blade looks like a latter knuckle-guard hilt mounted to an older Algerian or Syrian blade. (?)
