Can I drive this relay directly from a microcontroller pin?
Not recommended. The 12VDC coil draws more current than most GPIO pins can supply. Use a transistor or MOSFET stage, a flyback diode across the coil, and a separate 12V supply for the coil.
Can it switch mains AC loads?
The listing gives only the 5A DC-coil rating. Check the datasheet for the AC contact rating before switching mains loads, and keep the load within the stated current.
