These are only guesses since more info on each rose is needed for ID. Not knowing what zone you're in, my guess is ...

Tropicana

Midas Touch

Celestial

?

Baronne Prevost or Madame Isaac Pereire

Try helpmefind.com and remember to click 'refresh' to see more photos. Midas Touch wasn't available until 10 years after the park was built, but I imagine the original roses have been replaced, especially if it appears they receive little care.

I hope with your encouragement the powers that be will see that these roses get the care they need. A little water, nutrients and mulch isn't too much to ask. Good luck.

I'm thinking the last one might be an Austin. There are thousands of kinds of roses, with many moderns (and some old garden roses) not being all that distinctive. Don't put any publicly displayed names on any of these without first matching them with known plants that are without a doubt the exact same kinds, with the same morphology and fragrances.

I found the same problem in my park. No names, neglected. I decided to fix it. It looks much better now.

My Tropicana had a lot more petals and a longer bud.

First one may be Fragrant Cloud.

The second one could be any of several varieties but reminds me of Friedenspark Hiroshima, see picture here: Modern Japanese Rose varieties

I wonder if that first one could be SUNDOWNER. The yellow one might be SUNSPRITE. The third one I don't have any idea. The fourth one looks like AUDREY HEPBURN. The last might be GERTRUDE JEKYLL.
