No, there is no element named "stell". Nor to the best of my knowledge, are there ANY compounds called 'stell". Perhaps you mis-typed it and you meant "steel"? Steel is an alloy of primarily iron, plus some cobalt, carbon and manganese and a couple of other elements depending on the grade of steel.
Most towers are made of steel concrete, aluminum, and iron.
It hasn't. The current London Bridge is made of pre-stressed concrete.
Steel is made by mixing iron with carbon. The iron is melted with intense heat and then mixed with carbon. It can them be molded into knives, tools, or many other common things.
