Variations of the Lee-Enfield rifle (modified for accuracy), and the Boys .55 inch anti-tank rifle (sort of a predecessor to modern heavy sniping weapons like the Barrett M107). However, in the case of the Boys, it wasn't so much a sniping rifle as an anti-materiel rifle, and iron sights were used.
Besides captured weapons/smuggled weapons, and the M1 Garand, the primary US WW2 sniper rifle was the 1903 Springfield (30-06) during WWII. Besides captured weapons/smuggled weapons, and the 1903 bolt action Springfield (30-06) sniper rifle, the scoped M1 garand was the primary US Korean War sniper rifle. Vietnam War USMC snipers used bolt action hunting rifles; US Army snipers used the XM-21 Weapons system (aka the M-14 service rifle). The 101st Airborne (Airmobile Division Vietnam) was a unit; units will use what the rest of the Army uses...unless they appropiate it.
The Lee-Enfield rifle of 0.303" calibre.

Over 100 million rifles were used during World War 2.
During World War 1 the sniper rifles were mostly the standard issue rifle that had a telescopic sight or Scope installed. The three main standard issue rifles that were used and modified for sniper detail were: the British Lee Enfield, The German Gewehr 98, and the American 1903 Springfield.
They did not. However, during WW 2, the government purchased .22 TARGET rifles to be used to train service members in basic rifle marksmanship. Training was mainly for people that would not be expected to use the M1 Rifle on a regular basis- such as Navy, Air Corps, Women's Army Corps. .22 rimfire ammo and the rifles to shoot it were less expensive than the M1 Garand. I have one of those rifles in my collection (a Mossberg 44US)- and while they are very accurate, their maximum effective range is about 100 yards- hardly a sniper rifle.
By which side? The US and its allies used 7.62x51 for their sniper rifles. The North Vietnamese typically used 7.62x54R for theirs.

A sniper rifle is simply a rifle used by a military sniper. Just about every gun shop will carry hunting rifles. The type will vary depending on what you are hunting- squirrels, rabbit, deer, turkey, bear, elk or elephants. What you are calling a "sniper rifle" is simply a bolt action center fire rifle with a telescope.
Yes
You will have to define the term "Sniper rifle". It could mean anything. The only TRUE sniper rifle is a rifle issued to a sniper. They are simply rifles that are capable of long range accurate shooting. The rifles used by US military snipers during the Vietnam was were simply civilian hunting rifles with decent telescopes.
Mainly the US and it's allies, but all sides have used sniper rifles.

This is subjected to opinion but they most used sniper rifles are the Barret 50. Cal and the Intervention. The Intervention is the more commonly used of the two so it is considered the best sniper rifle.
They used sub machine guns, sniper rifles, rifles, pistols, anti tank weapons, and machine rifles. Examples: The Thompson, BAR (Browning Automatic Rifle), M1A1 Carbine, etc....
A sniper rifle is a precision rifle that has a telescopic sight which allows operators to target an object that is far in the distance. Sniper rifles are used in military combat.
There are some accurised variants of the M16, SA80, and other 5.56 rifles out there which are designed and used as Designated Marksman rifles, but, in general, the 5.56x45 and .223 Remington cartridges really aren't the ideal choices for a sniper rifle.
Springfield The M1903-A1 and M1903-A4 .30-06 rifles with a variety of scopes were used by most US snipers during WW 2. The Unertl 8X was the scope preferred by the USMC. the military also made limited use of M1 garand sniper rifles.
