I have a feeling that the three girls (ladies) will be compensated. I sure hope they will.

California to Compensate Jaycee Dugard With $20 Million
The difference between this case and Jaycee Dugard's case is that offender in Jaycee's case was on parole. There were supposed to monitor him and they didn't do it well. Whereas in this case Castro was not on parole for anything.
None of the other victims (Elizabeth Smart, Shawn Hornbeck, etc) got compensation from police as far as I can tell. You can not usually sue police for not solving your case.
