Lead is a chemical element, not a mixture.
Lead is a poor metal and (or) a metalloid: it has some amphoteric properties as well, like bismuth or arsenic. It has some fine metallic properties though.
In Chemistry things are described as element, compound, or mixture Pewter is a mixture as it is made up of a combination of different compounds.
No. A recent example was when the FBI gave up insisting that all bullets from a given melt would have the same mixture composition. Bullet melts are generally made from quite variable scrap, (lead, antimony, tin.) and due to their different specific gravities, they are not evenly distributed throughout the melt.

Yes, lead is a metal.
Lead metal
Steel is not an element at all ! It is an alloy (mixture) of mainly transitional metals. (Fe, Ni, Co are transitionals) Lead, Pb, is not a transition metal but post-transional (group 14) (Transition elements are in group 3 to 12)
Lead is a soft ductile metal.
