I believe this to be all of them.
Data about active shrines
Wayshrines activate roughly every 10 minutes, and are clickable by only one person per activation. Being in a group (not raid) will grant credit for the quest if one person clicks the wayshrine.
These are used for Wayshrines Of The Celestials as well as Pilgrimage, granting one of four buffs, or causing a massive fire AoE that will pull nearby enemies.
The buffs and quotes for each are: (some assistance on the unknown ones would be great, add as a comment in reply and I'll add them)
Fortitude of Niuzao "Though blood floods the ground, the mountain is unmoved."
Wisdom of Yu'lon "The truth shines brightest in clouded times."
Chi-Ji's Hope "Hope's fire grows when the flames come together."
Xuen's Strength
The AoE is
Ordos' Burning Sacrifice "The shrine was corrupted by Ordos!"
