Can you get a clear pic of the first one? It doesn’t look like cudweed… but… you pulled it instead of taking a pic of the growing plant. If you have cudweed, you might consider keeping it for the american lady butterflies… Agree on poa annua. I think that planting Bermuda is a huge mistake… Did you ever try to dig that junk out and plant flowers and vegetables?

The beauty of Bermuda is if you’ve had it you’ve got it! A worthwhile caveat here would be you must have a full direct 6-8 hours non-interrupted sun per day. It hates lingering shadows worse than weeds. Sunshine it, feed it, water it and then try to kill it with your lawn mower! Seriously, mow the heck out of it. If you let it put on a seed head you’re not mowing close enough nor often enough. Now to add insult to injury, when you start seeing runners, core aerate the fool out of it! Git’er done and as Ms Lisa would say, “best wishes!”
