Picture 3 looks like it might be Calendula.

#2 looks like cosmos. Will get 24-36" high.
#3 looks like larkspur to me.
#4 cornflower, bachelor buttons. They sprout and grow fast.

This type of "wildflower" mix is at least half species native to Europe and Asia. I'm not at all sure why you are pulling up the plants to photograph them. Did you sow too thickly?

#1 resembles smart weed.I've thrown out seed mixes before and lots of weed seeds in the ground came up with them.#4 looks like a grass and #5 looks like pigweed but the photo has sunglare and you can't see the leaves straight on,but sure looks like pigweed.I had the same plants coming up on my wildflower garden.I don't buy mixes anymore because like the other gardener mentioned they usually contain non native plants and I enjoy creating my own mixes using only natives.In mixes you can't control what plants will grow where, so you have larger plants shading shorter ones.If you mix it yourself you can sow the taller plants behind the smaller ones.I've gotten lots of seeds from Wildflower Farm but it bothers me that they sell a lot of alien plants like Dames rocket,foxglove and African Daisy. I would have more respect for them if they dropped all the aliens and expanded their native wildflowers.There's a multitude of beautiful natives they don't offer.Prairie Moon and a lot of other seed sellers only sell true natives.

I buy mostly from Native American Seed. They sell natives but most are for the southern plains.

I find NATIVE AMERICAN SEED CO. mixes to contain truly native species. Other wildflower mixes use non-native species that will occasionally naturalize or even become invasive, depending on your climate and soil. The non-native species have dependable germination, which is why they are used.

While NAS Co. focuses on Texas, most species are usable into the central plains states. You can check the native and naturalized range of native wildflowers by using the Ladybird Johnson Wildflower Center PLANT SEARCH feature of their website. Enter either a common or scientific name and click on the GO button. If you enter "bluebonnet" you'll get one result for Lupinus Texensis. If you enter "lupine" or "lupinus" you'll get 59 species as various species are found across the country.
