I bought these plants from the nursery all were marked as being "Indian Summer Rudbeckia" but they all look different. This first image shown are flowers that were in the same seed pot together but they come up on different stems. Should I dig them up and divide them? They don't even look like the same flower.
The last one looks like the best match for 'Indian Summer' as pictured in Plant Files http://davesgarden.com/guides/pf/go/54127/ I don't know my Rudbeckia cultivars well enough to venture a guess what your other ones are.
I don't knpw any of the botanical names but the top orange one and bottom yellow looks like garzania. And the small orange looks like some kind of zinia.
The top ones look like they could be Rudbeckia hirta 'Cherokee Sunset,' which is a seed grown mixture of double and semi double flowers in various colors. http://davesgarden.com/guides/pf/go/71193/
