I'm afraid your description of the problem is still rather... opaque.
>From your original post it looked like the answer would be:

    def replacer(target, replacements):
        for replacement in replacements:
            if "/" in replacement:
                target = target.replace(*replacement.split("/", 1))
        return target

    print(replacer("Hello my name is Richard",
                   ['Hello/Hi','my','name','is','Richard/P']))

but in your new description where you start talking about word indices
I have no idea if that's what you actually wanted.
