Depends on the choke. MOST chokes, including full choke, can safely fire slugs. Some makers of adjustable chokes recommend that slugs NOT be fired thru their chokes. A very few chokes, such as the Extra Full chokes used on some turkey guns should not be used for slugs.
with the wingmaster barrel you can only shoot lead, but if you change the barrel to a slugster you can shoot slugs and buckshot, they also have a barrel for steel shot to.
That will depend on whether the choke tube is rated for steel shot or not.

From Mossberg's website:"Can I shoot slugs or buckshot through a "smoothbore" field barrel with Accu-Choke™ tubes? (500/505/535/9200/88/930 models) Yes, and with sabots or rifled slugs, the more "open" the choke tube, the better the accuracy ("Improved Cylinder" recommended.) The "full" or "modified" choke tubes are preferred for buckshot loads. Slugs, buckshot and steel shot loads are not recommended for use with an extra full "turkey tube" installed, due to the tube's tight constriction. Do not fire any load without a choke tube installed, doing so will damage the internal choke tube threads. "
If it was made to shoot steel shot and has interchangeable chokes.
It is generally not advisable to shoot slugs through a full choke, although people argue about this all the time. Personally I use IC choke for Foster slugs. Sabot slugs are designed to be used in rifled barrels only. You can but it proves a little dangerous. But the biggest factor is that the lead slug squeezes through such a small hole it deforms and your accuracy goes to crap.
Depends on the load and what the maker of the choke/shotgun say.
Yes. I duck hunt and my primary gun is an 835 Ulti-Mag. It is perfectly suitable to shoot steel through the 835, but make sure that your choke tube is suitable to do so. Yes.

No.
No.
As long as the barrel was made after 1950 and does NOT have a full choke, you will be able to shoot steel #2 or smaller.
The short answer is "it depends". Need more information.
