A carbon steel wok, once it is seasoned, requires very little maintenance. A quick swish in hot soapy water is all that is required to clean it. Stainless steel woks never acquire this "seasoning" and so tend to stick when cooking.

I guess you could...but you would only be able to do one at a time.

No. Teflon takes the place of the seasoning process for steel or iron woks.

There is no best known brand of stainless steel wok. The only factor in buying a good wok is that it should be a carbon steel wok that will conduct the heat evenly.

If you have an electric wok or a non-stick wok, you do not season it.

If you have a traditional carbon steel wok or cast iron wok, then you need to season it.

The best way to season a carbon steel wok or a cast iron wok is to use the so-called 'salt seasoning method'. It is discussed in detail (along with other ways to season or re-season a wok) at:

If you do not season a new carbon steel or cast iron wok food will stick to it and you won't be able to cook in it.
