Solved IDs please

I have 3 plants that have suddenly appeared and I have no idea what they are!
This one seems to be taking over!


This one is quite nice but not in an ideal spot



and 2 of these have appeared



Any help would be great

 

First one looks like one of the Persicaria tribe and yes they are spreaders, but not that hard to dig out.
The second looks like Linaria purpurescens, another good seed provider.
Finally that is one of our lawn weeds , Broadleaf plantain.
