Multiple device on VAC transformer
The simple answer is no. Phantom power requires a DC connection to the microphone and you would end up connecting all the microphones together in parallel for both power and signal.

The longer answer is yes, you could have a single connection to your 220V power source but you would need to use an isolated DC to DC converter for each microphone. It's probably cheaper and easier to buy a multi-channel phantom power supply that does exactly that.
