In the universe they are initially made in supernova explosions. These then become parts of other stars, planets and celestial bodies. Some are radioactive and decay into daughter elements which are usually after iron.

how made iron?

Iron is an element. It isn't "made". Iron is obtained by digging iron ore out of the ground (mining) and processing it to separate the iron from oxygen, sulfur and other elements to which it had become chemically bound over the millennia. According to modern astronomy, cosmology, and physics, iron, like all naturally occurring elements, is made in stars, from the fusion of smaller elements. Fred Hoyle proposed what's called 'nucleogenesis', or formation of elements in the stars. Hydrogen plus Hydrogen makes Helium; then on to Lithium, Carbon, Nitrogen, etc. Iron is the last element a 'normal' star can make. All elements heavier than Iron are made in the explosion of a supernova.
