1,3,4, and 7 all look like older Enfield bayonets. Since Enfield is a design, it was independently made by many different British Colonies. 1907 wilkinson is definitely one. Google your best description of the markings and it will throw back all the info you need. They all, except maybe the shorter one, look like WW1. WW2 had shorter bayos, and before WW1 they mostly looked like spikes, rather than knives.
