No, however you are able to get a sniper scope for all of the bolt action rifles.

Short Magazine Lee Enfield. Hands down, the king of all the bolt action battle rifles.
There were multiple bolt action rifles used in World War 2 on all sides. There were also semi and full-auto rifles used on all sides.
No
Also known as 7.62 NATO, this was the standard full powered rifle caliber for all NATO nations. Rifles included the M14, the British L1A1, the Belgian FN FAL, and even India had a bolt action version of the Enfield in that caliber. It is also used in the M60 machinegun, various sniper rifles, etc.
Well it depends on if you are playing hardcore. Otherwise the M95 is the best, being a magnum sniper. Also use magnum ammo to increase damage on it. Now you See if you are playing Hardcore then basically all of them are the best because they are one shot one kill so the best would probably the VSS SNYPERA but if you need the best accuracy then you would/will want the GOL sniper.
ALL OTHER THINGS BEING EQUAL- yes, the bolt action is typically a more accurate rifle. However, there will be exceptions.
You Have To Complete ALL the sniper marksman challenges with all the sniper rifles to unlock the gold Dragunov.
Considering the size of most pellets, there is not much of a reason for a large Bolt Action air weapon. But yes there are several bolt action pellets guns and rifles. An example is the Crosman 2240. There are several "High Powered" air rifles, PCP's, (PreCharged Pneumatic) that also use a blot action, The Benjamin Rogue 357 the Marauder and Marauder pistol all use a bolt action system. I own at least 5 or 6 bolt action air guns.
Weapons of all types including sniper rifles can be found in chests, lockers, sometimes in skag piles and quite often dropped by enemies as you kill them, there are lots of sniper rifles to be found, so get looking and you can buy them
