The spear-head shaped larger leaves will, I reckon, be some sort of soft thistle and, I bet, if pinched off, they will ooze milky-white sap.
I'm holding off on the little leafy rosettes for the moment, but they do seem to be "cress" related. But then I'm also thinking "lesser celandine" as a possibility: probably not, but give 'em a few more days and they will be more easily identifiable.
