    The first one could be Ribes aureum (syn. Ribes odoratum)

    5th one is something in Boraginaceae.

    The overall view looks like it, but the number of petals is just four as I can see (coelacanth also mentioned in the image name - "veronica-like").

    Maybe a better shot of the flowers in #5? You're right, it is likely 4.. but I can still imagine 5 petals.

    For all the tiny flowers I captured in the picture not one is in focus and shows all petals. Whoops. The one outlined looks like it has 5 petals (?) Ooh, Verbena bracteata seems to fit the bill.

    Could #3 be a Bidens?

    Could be, although, an uncharacteristic one. Bidens have two distinct types of involucre bracts: vertical, appressed to the flowers and horizontal, usually larger than in this picture. The leaves usually look sharper than in this plant.
    To be sure, you have to dig inside the flower head to see individual flowers. In Bidens, each flower is surrounded by scaly bristles at the base of achene and has two or more barbed awns on the top of achene:
