I believe that is annual ryegrass. Is that one of the seeds in the Contractor's Mixture? I got some in Scotts Sun and Shade Mix. It seems to go away or be less noticeable after a few cuttings.

I just happened upon this thread and want to share my opinion on no. 1: it's not Henri Martin. HM is a moss rose and more upright. And I would say more purple, but that colour is hard to photograph. Beautiful roses, both of them! Buds of Henri Martin

Here’s a link to the WB over W stamp. Wallace Brothers/Wallingford (a town in CT where it was manufactured). https://queenofsienna.wordpress.com/2014/08/26/wbw-900/

This may come too late for your project, but neither of the blues in your photos match Farrow & Ball colors, at least on my screen. For reference, I have a full color collection card to which I compared. Blue Ground for the first and Cook's Blue for the second are probably the closest but are not matches. If you are sure these are Farrow & Ball colors, then you would need to check for archived colors unless the online images are somehow color distorted.
