Good catch, I had a closer look and could only identify one more, the topmost one on the right hand, and it seems to say "Awareness". (not sure its visible in the resolution here, its at the very bottom of the screen)
Regarding the meaning of the wristbands we can only speculate, as there seems to be no official comment about those. (At least I was unable to find any.)
My theory is that the bracelets represent human traits that lead to suffering. Gabriels motivation for his/her actions result from the view that God has blessed the humans with so many gifts and his unlimited love and understanding, but they have not earned it.
Gabriel thinks that humanity can only show it's best side and true greatness when they are suffering. Gabriel therefore wants to literally bring hell to earth, so that those who survive all the horror and pain are really worthy of gods love.
The wristbands indicate that Gabriel is the bringer of humanitys suffering.
Also notice that the bracelets are the ones of a mental institute, the same one that Isabel was wearing when she jumped off the building, probably somehow influenced by Gabriel.
