Well, the primary is formed by light which reflects inside the rain drops once, and the secondard by light which reflects twice. For the other answers read about how rainbows are formed at

The secondary rainbow has reversed order of coloring and more internal reflections so it is dimmer. 51 degrees vs 42 for the primary
