First one has the look of Catananche caerulea.

first one Chicory [Chichorium intybus]
the second one is one of the Hieracium but with out close up of leaves and sizes etc difficult to say.
third one could be the same genus or a totally different one. there are so many that are very similar.

Thanks the 2nd & 3rd pics are the same plant. I just wanted to show another perspective.

with the yellow dandelion types you need to show the leaves and how they clasp the stem. also the arrangement of flower buds on the stem. there are lots of Hieracium species in the uk so probably similar in the USA.

Agree on the blue one as chichorium.
With the yellow, Crepis or Hawksbeard?
In the daisy family more than dandelions?
Quite tricky from the photos though, they're not entirely clear...

I replaced pic #3. Hopefully this makes a difference.

How tall is it? the stems appear smooth that's why I went for the Hierscium [hawkweed] genus. rather than the hawksbeard. It could be cat's ear that has similar flowers and smooth stems.
the daisy and dandelion are all in the same Family Compositae or asteracea depending on which source you use Darren.

but without the leaves and how they are arranged at the ground and on the stem it is difficult to be certain. also recent DNA of these plants often throws up hybrids too.

It's about 2 feet tall. I"ll have to go back to the site I spotted this. It's growing in the grass so it's hard to make out the leaves. I'll try to uproot a whole plant.

no don't uproot it please. it is a shame to destroy them just to satisfy my curiosity.

I'm wondering about Catsears. Could you break a stem and see if the sap is milky or clear? Hawkweeds have milky juice and Catsears don't.

I saw this in a local field about 2 miles away while on my early morning bike ride.
