It looks like the bugs or slugs are eating up the second one, so maybe it won't be a problem. I have no idea what you have though. It looks like the first one is about to bloom. Pull it up before it sets seed. Sorry I'm not more help.
The first one resembles pineapple weed. Or, it's not a weed at all because it also resembles cosmos. A bird could've planted it. Take a pic when it blooms and I'll have a better idea. The second one looks like a type of plantain. Maybe buckchorn plantain? If you find the answer, I hope you'll let us know.
I'm a Californian and we have the same weed that's in your second photograph. I think it's called dock. I found this pdf that contains weeds in your area. Maybe it will help. I'd dig them both up before they can spread.
