Yes
Steel is an alloy- which is a compound, or intermixture. So it is not an element or pure substance.
No; steel is an iron-carbon alloy. Stainless steel is an alloy of steel with chromium added. Stainless steel is usually 13-25% chromium (by weight).
Gold is a pure substance (element), water is a compound, steel is an alloy, and air is a mixture of gases.
Steel is the name for several alloys of iron with other substances to improve its strength, or its corrosion resistance, or some other property. Since there is no one substance called 'steel' but a whole group, then it cannot be a pure substance. By chemistry definitions there are only 2 pure substances, elements and compounds.

Iron is a pure substance. It's an element (Fe) and a bar of Iron is no mixture. If it was pure iron, then by definition it would be pure. However iron is rarely pure, it is usually in alloy with something.
The pure substances from the options provided are a rod of steel, a cube of sugar, and a block of wood. Steel and sugar are pure chemical compounds, while wood is a homogeneous mixture of different compounds but is considered a pure substance in the context of the question. Leather and milk are mixtures of various compounds and are not pure substances.
pure substance, propanone

Pure substance
Methane is a pure substance.
iron is a pure substance. A pure substance is any form of matter that has a uniform composition and cannot be separated by physical methods such as filtration. A mixture can be separated into its components by physical means. <<>> Most nails are made from mild steel so they contain a small amount of carbon around 0.2%
