Hello, our boiler just died...The cast iron of the boiler got cracked...so we are in the search of putting a new boiler (works with natural gas). We have the conventional cast iron radiators in the house that works with hot water. Can we use the tankless water heater to heat the radiators? if so, how much would they cost, labor + parts? I live in the Bay Area, CA....

It is possible to do it, but not practical. A tankless is not made for this purpose and won't heat the water as hot as a boiler would. Also the the tankless is not made to accept hot water as input and may be damaged by circulating the water through it as often as necessary to heat up the radiators. Installation of a tankless would only be slightly less than replacing your boiler. Do it right and get a new boiler.
