chemical property
While stainless steel is an alloy of steel, the primary difference between stainless steel and other steels is that the stainless steels have a high percentage (about 10% or even more) of the element chromium in them.
Chromium
Yes, stainless steel can be magnetic depending on the specific composition. Austenitic stainless steels (such as 304 and 316) are generally non-magnetic, while ferritic and martensitic stainless steels are magnetic.

The most rust resistant stainless steels contain nickel and chromium in addition to iron.
Stainless steel is an Alloy steel because it contains chromium as an alloying element - steels without alloying elements are called carbon steels.

Stainless steels
Yes, stainless steel can be magnetized to some extent. The level of magnetic properties can vary depending on the specific grade of stainless steel and its composition. Generally, austenitic stainless steels (e.g. 304, 316) are not magnetic, while ferritic and martensitic stainless steels can be magnetized.
No, but most stainless steels will be fine becuse the buckle content is so low.
Chromium is present in stainless steels, tool steels, zircaloy and other.Many compounds of chromium are used in industry.
Diving knives are made from highly stain resistant alloys, e.g. H1, X15TN, titanium alloys, etc. Regular knives can use either stain resistant or plain carbon steel. Special stainless(stain resistant) steels used in dive knives resist corrosion very well, but the downside is reduced edge holding ability compared to carbon steel or conventional stainless steels. Also, diving knives very often have rounded or no sharp tip to avoid accidental piercing of the suit or other underwater equipment. More on knife steels in the attached link.
