Can Arduino Nano Handle eight 220v AC current operation at a time?

Hellow good people. I want to make a home automation system with my arduino nano. I want to control 6 220v lights and 2 ceiling fans with two 5v four channel relay board. I also planned to connect separate 5v power supply for the relay boards too. Though these things are powered by high voltage AC current. So, I just want to be sure that can Arduino nano handle eight 220v AC current operations at a time? Because AC current is dangerous, I just want to be confirm before taking final step. Please someone help me. Can I do this project with arduino nano?

The relays handle the high voltage, the Arduino control's the relays. All is separated, you are good.
