Will react native support at least version 15 of the SDK? If not, how can I use react native apps on Android 4.0?
My app users may use old phones for now (health & medicine).
React Native supports API 16 and newer. If you need API 15 you can't use React Native.
Supported operating systems are >= Android 4.1 (API 16) and >= iOS 7.0.
https://github.com/facebook/react-native/blob/master/README.md
Only about 4.3% of android users are on devices running 4.0.x or older.

Is there an existing React-Native library to implement Here maps and navigation, or do I have to implement the Here SDKs natively for both platforms?
You need to implement native module for both iOS and Android to use Here SDK from React Native apps. If you are using HERE SDK 3.x, following would be a good example how to do it.

If you are using HERE SDK 4.x, you need some modification to the above example to adjust the difference of the interface between 3.x and 4.x.
I can not find the Expo support for Android SDKs. Android 4.4 is no longer supported since Expo SDK v31.0.0 version Here. Since Expo v31 now is 6.0
Where can i find more information about Android SDK support?
You can see it in the docs:
The minimum supported OS versions are Android 5+ and iOS 10+
If you need to support older versions, you will not be able to use the managed workflow.
Android 5.0 is Lollipop, API 21.
I'd like to update my app from old expo 22 to current 36.
which minimal android and ios versions for expo sdk 22 and 36?
or is there difference in minimal version to run app builded with expo 22 and 36 on android/ios?
As far as I'm aware all versions of the Expo SDK support Android 4.4 and greater (Android SDK 20 and greater). There is no need to set minimum Android SDK. If you want more control over the metadata you need to eject from expo and use ExpoKit.

Does React Native have support for Windows Phone and BlackBerry? Perhaps Java Phones too (Jad and Jar). Thanks
Yes you can build react native apps for the Windows platform, including windows mobile phones and X-Box:
https://www.microsoft.com/developerblog/2016/05/26/creating-universal-windows-apps-with-react-native/
There doesn't appear to be any support for Blackberry, however.
And... I wouldn't recommend building any apps for the Windows platform, as it's basically dead: https://www.theverge.com/2017/10/9/16446280/microsoft-finally-admits-windows-phone-is-dead
