None of those are native species in California. Spotted spurge is native to eastern North America. It can be useful to distinguish between weeds, which are wrong plant in wrong place, and invasives, which cause problems everywhere. Dandelion can be a weed, but also can be useful, Purslane is like that. None of those are considered invasive in San Diego, that requires removal. But the other aren't useful and spotted spurge is toxic.
