The dyes which you cite are all commercial dyes and have been used to sensitize emulsions for about 100 years. The Lumiere brothers sensitized their color process, Autochrome, in 1907. Their silver/bromide emulsion contained Orthochrom T, erythrosin, and ethyl violet (which is not on your list). see:

Modern films contain dyes which are typically cyanine derivatives. These dyes are not stable, but since they are exposed to light only briefly, that does not matter. One dye which has been used to sensitize for red light is Sand's SDA3057, which has been discussed on APUG.
