Agfacolor Ultra-K, Fomachrom II are to be processed in a classic Agfacolor process.
The first is a negativ- the second a reversal-film.
You did not specify the type of Orwocolor film. Thus I cannot even state whether it is a negativ- or reversal-film. Anyway, the chance that you got a modern formula Orwocolor is slight, thus I assume it belongs to those processed in a classic Agfacolor process.
