And a Black-eyed Susan vine mixed.
We don't sell plants here but I know for a fact that online catalogs sell those. I just ordered a dolphin plant myself. You can also check large nurseries who carry indoor plants. The black-eyed Susan vine is normally found at local nurseries or you can grow it from seeds.
They have been beautiful for several years. This year the plants look the same but the flowers have now petals.
This could be a case of too much nitrogen and not enough phosphorus and potassium.
Make sure to test your soil for deficiencies and pH swings, which can cause deformed blooms.
I don't see any signs of disease, so it is likely that the nutrient ratios are off.

the one that's not blooming of the different colors
Are you deadheading the blooms? They should bloom from midsummer to frost.

All my others were perfect
Looks like aster yellows, a virus transmitted by leafhoppers.

I planted some Black Eyed Susans a few years ago. I took them out of the garden because they spread too much. However, now they are showing up absolutely everywhere as bad as the weeds. How do I get rid of them? Just pull them up?
You can dig them up. I found out they don't "pull" up. If there are too many and that is too labor intensive you may want to use a non-selective herbicide with glyphosate.
Here are some alternatives to chemicals you may want to try:

Plant wilting. Only "fail" this year! Leaves and flowers drooping 2 weeks after planting. Not in full sun.
If you're not seeing powdery mildew on the plants, there are two possibilities that come to mind. Your plants like a neutral pH soil, so if you've fertilized them, it may be too rich for them. The other possibility is that they may be wanting more sun.
Check for powdery mildew and leaf spot: https://www.gardeningknowhow.com/ornamental/flowers/black-eyed-susan/rudbeckia-leaf-spot.htm
They seem to be bending and dying earlier this year. Why?
Unfortunately, your photo did not come through. Wilt can be attributed to many things, from disease to pests nibbling on the roots, even to heat!
What I can do, in the meantime, is point you to an article that will help you with their care. This can help you rule out environmental factors, knowing that you are providing proper care.
