The souls all fell ages ago. They didn't have the same experience or meet the same monsters Frisk did. Undyne wasn't the captain of the guard, if she was even alive yet. Mettaton wasn't a robot, and Alphys wasn't the Royal Scientist. Who knows about Muffet, but she probably wouldn't bother with someone who didn't hurt spiders. Canonically, some of the souls did reach Asgore, and Toby heavily implied in a tweet that they all did. The locations of their gear don't necessarily mark where they died, just where they lost their stuff. The magic to change the color of your opponent's soul is likely the result of the previous Royal Scientist's research, before he was, regrettably, erased from existence.
