Your link says these are elements commonly found in steel, not that they are all required. In fact it says of phosphorus and sulphur that they are generally undesirable.
We don’t need to make a steel sword, an iron sword could do.
Either way you would definitely need carbon, but as you say that’s pretty easy. I don’t think any of the other elements are absolutely required.
Steel requires only iron and up to about 2% carbon
Rest are minor alloying elements used mainly in modern steel alloys to improve the steel beyond what just carbon steel could do like for example stainless steels
