Since you're already using concrete, not much point in using the lighter, weaker, and more expensive aluminium. And lead is really weak, environmentally hazardous and more expensive than iron.
Steel reinforced concrete is concrete with rods of steel running through it.
Steel is heavier than concrete for the same volume, however steel buildings are generally lighter. This is because steel buildings utilize high strength of steel, so volume of steel in steel buildings is much smaller than volume of concrete in concrete buildings. In another words in steel buildings much less volume of material is needed for the same strength compared to concrete buildings.

Concrete can be reiforced by using steel; steel can not be reinforced
Steel reinforced concrete is concrete with rods of steel running through it.
The steel rods are there to strengthen the concrete - making it reinforced concrete.
how calculate steel in concrete
The basic matetrials were steel and concrete.
Concrete is much more fire resistant. This is shown by the design of reinforced concrete structure where the steel is placed within the concrete. A major reason is that the concrete protects the steel from any fire. Steel only construction requires the steel to be covered in a fire protection material.

Concrete is unpredictable compared to steel...
Mainly re-enforced concrete (concrete that's been set around steel rods). The cables are made from many long strands of steel.
That depends on what the foundation is for and what local law says about. Technically, you don't need any steel, since there are other ways to reinforce concrete.
