Does anyone know what varieties I have?
There are so many Iris varieties now that even experts have trouble telling them apart. Better no name than the wrong one.
As Dee said it is pretty much impossible to ID on pics alone. All of them except for #5 are quite old. They would be considered Historic Iris. The ones with the really long falls are the oldest. #5 has ruffling to the edges which shows it is more recent than the others. On the link below, you can check out pics of old irises. You'll see what I mean by being able to make a time frame of when an iris came from by the look of the flower.
