We are not able to send people in person to diagnose problems. However your photos are excellent for diagnosis. The first photo, 6182, is rose black spot. https://solvepestproblems.oregonstate.edu/plant-problems/roses/black-spot and https://pnwhandbooks.org/plantdisease/host-disease/rose-rosa-spp-hybrids-black-spot
Photo 6187 is rose mosaic virus, and 6191 looks like more advanced case of the same. https://pnwhandbooks.org/plantdisease/host-disease/rose-rosa-spp-hybrids-rose-mosaic
