Yes, this is indeed possible. You may refer the homekit_switch example which will enable Alexa, Google Voice and HomeKit (Siri) control.

this is IDF code, whether support use arduino IDE code for RainMaker use for homekit,google home,alexa? whether have arduino demo source code for these?

Unfortunately, we do not support HomeKit in Arduino right now. Only RainMaker (and hence, Alexa and Google) is supported.
