Browning barrels will not work in Remington or Savage, and vice versa. The big stumbling block is the ejector. On the Remington and Savage the ejector is a single hook brazed to the rear of the barrel extension. On the Browning the ejector is a pair of hooks. The bolts of each are slotted to fit their proper ejector. The wrong barrel won't clear the bolt and the ejector will get hammered if you try.
Barrels of the Remington and Savage shotguns have a limited potential to be interchangeable, due to the shell stop cam cuts. The cam cuts are beveled notches on the exterior of the barrel extension. They work the cartridge stop that prevents a second shell from feeding out of the magazine.
Slight variations of dimensions through the decades allows some barrels to work in both models. Like I said, "some". Most do not. The only way to be sure is to try it. Frist, try feeding dummy rounds, and if that works then test fire. The best idea is to buy the correct barrel for your gun.

Can you please give us the model?
No. The Auto 5 and the Model 11 use the same design, but there are a few significant differences. The most important one is the design of the ejector. The barrels are not interchangeable.
Your best source on information would be to contact Remington via their web site.
Remington did manufacture a John Browning designed rifle. The Remington Model 8, semi-auto rifle was made from 1906 until 1936. The improved version, the Model 81, was made from 1936 until 1950. Remington also manufactured the Browning designed Auto-5 shotgun under their name as the Model 11 in various grades and gauges.
Depends on when it was made.
Search web for Remington model 11. web info for inertia operated Browning a-5 is nearly identical.
Remington 11's are essentially Browning type shotguns with lesser values because of the name brand associated with the latter manufacturer. It is possible to find a Remington model 11 with an extra barrel with a different choke. The installed barrel and the extra barrel should have serial numbers.
