The price of a .45 caliber long gun flintlock can vary widely depending on its condition, maker, and historical significance, typically ranging from a few hundred to several thousand dollars. The number "7684" could refer to a serial number or model number, but without additional context, it's difficult to determine the exact age or value of the firearm. Flintlock guns were commonly used from the 17th to the early 19th centuries, so if this gun is a flintlock, it could be over 100 years old. For precise information, consulting an expert or appraiser would be advisable.
Impossible to answer with the information you have provided. Sort of like "How much is a V-8 car and how old is it?"
Varies. European Jager rifles were shorter, and fired larger bullets. The Pennsylvania rifle (miscalled the Kentucky rifle) were of smaller caliber, but longer- about 5 feet.

Who made it, what caliber is it, is it a rifle, shotgun or hadgun, how long is the barrel, is the barrel round or octagon, what is the stock made out of, what is the serial number(if any)?

In most cases, if you give me only a serial number, and no info on make, model, caliber, then no. A serial number is not unque, or it would be 20 numbers long.
no
From the very beginning. The American War for Independence against the British was waged with Brown Bess and Charleville flintlock muskets, as well as any number of homegrown Jaeger rifles, Kentucky and Pennsylvania Long rifles, flintlock pistols and more. Actually this was all before we were actually the "United States of America." Before we were a nation, we had guns, and have had them ever since.
