No, you could not describe it as an insulator, though it is less conductive than many other metals like copper, silver, and aluminum. You may be thinking of insulating flasks made of stainless steel. These work because they are double skinned, on the same principle as a thermos flask.
No-it is a very poor insulator
Ceramic is an insulator, where stainless steel is a conductor of heat. Heat transfers more rapidly through stainless steel than through ceramic.
No, a sink is not a conductor. Sinks are typically made of materials such as ceramic, stainless steel, or porcelain, which are insulators and do not conduct electricity.
Yep, you can weld steel to stainless and you can weld stainless to steel. You can use steel or stainless welding rod in either case but the steel or steel welding rod will of course rust.
Well, the answer lies in the question; by saying 'real' stainless steel, you are implying that there are fake metals which go under the name 'stainless steel', thus the difference is that the stainless steel in refigerators is actually stainless steel, and the fake stainless steel is not...thus your question is answered...
Steel is a conductor and not an insulator.
No, Stainless steel is not porous. Steel how ever is.

Steel and stainless steel tend to weigh around the same, however, stainless steel can sometimes be a bit lighter.
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.
