Hawk's Beards, Hawkweeds and Hawkbits

I'm still finding IDs of these challenging so my first step is to document these prolific determined flowers. This page is for the unknowns, not the relatively easy to identify yellow flowered weeds (sow thistles, nipplewort, hedge mustard, wall lettuce, goat's-beard, celandine, greater and lesser, wild rocket)

no initial rosette or it's withered by now (will move those leaves at the bottom and check), alternate stem leaves

I've been watching this one for a long time as it's quite near me and easy to walk past and keep an eye on it. Full flowering after ?? weeks. 23-6-2018

damn yellow composite

Beginning of June 2018, it has flowered and no one disturbed it. I'm wondering if it's the same as the "damn yellow composite" from August 2017, below.

this is the plant above a couple weeks before when the flowers were just opening

damn yellow composite

2 months before, 20-4-2018, very red at the base of and centre of the leaves

damn yellow composite

two weeks before that, 7-4-2018, initial rosette of red-centred toothed leaves

2 weeks before that 23-3-2018, the first time I noticed this plant

damn yellow composite

around that time, plants were starting to self-seed, here are two more from that time, same plants I'm sure

damn yellow composite

this one I'm not so sure of, looks slightly different, less red, less pronounced toothes on the leaves but the one on the left above is something between this one and the one above right so maybe this one is just a younger example

August 2017

I have recently come across the term DYC (damn yellow composite) and this is an excellent example of one. I cannot identify it. To me, this looks just like chicory but I cannot find that chicory ever has yellow flowers. (If you have any further info, please do get in touch, julie at gardenwithoutdoors.org.uk, thanks).
