Are these all weeds?

Out of curiosity how big are these images?

Do you want them? (One definition of a weed is a plant growing where it is not wanted.)

Anyway, apart from the first, these are not common garden weeds. I'd need to see (clear images of) flowers to be certain of identifications.

to see flowers to be sure.

Almost certainly a weed.

The plant at the bottom left is Perovskia. Not a weed. I can't identify the plant at the top left.

are Linaria purpurea, Veronica spicata and Veronica longifolia). The first is a cultivated plant that often goes wild, whether the last two are usually found as cultivated plants.

Or, might be something on the lines of Sorbaria.

The first photo is the only one where you have what almost everyone would agree is a large, weedy plant (behind the Perovskia aka Russian Sage, not a weed).

The second photo has some weeds mixed in with what might be a Veronica (speedwell) cultivar, not a weed.

Any plant that you (1) don't like that is (2) growing where you don't want it to grow might as well be, for all intents and purposes, a weed.

Throw in aggressive spreading and seeding, and even otherwise pretty plants will end up on many "weed" lists.
