Hi

How to find out which BLE version is supported for a given Nordic SDK + SoftDevice. 

From which version of Nordic SDK is compliant to Bluetooth 4.2 ?

The NRF52 series supports BLE 5

The specific softdevice version will depend on the exact NRF52 SoC. Examples of softdevice versions for the NRF52 series include s132 and s140. 

The compatibility matrix for each NRF52 SoC model from this link might also be useful.
