>>93197841>Can you wear two rings simultaneously?
Hal did it with green and blue (If you count the orange power battery as a ring, maybe three)
Guy did it with a red ring and a violet ring, later with both a red and green ring.
Kyle once wore 6 different rings and an orange lantern construct at once, but it was too much for him.
Krona wore all seven before being killed.
So yes, it's possible, but not necessarily easy.
