My speculation....
Stoneward,
Edgedancer/Truthwatcher,
Dustbringer,
Elsecaller....
Stoneward- Time in Amaram's army, when no one could hold ground against Helaran Davar, Kaladin killed him. He stood when others fell.
Edgedancer- Grew up as surgeon, took the bridgemen who were forgotten and gave them new lives. Cares for others and healed them whenever he could.
This should be noted that my bid on Kaladin being a potential Truthwatcher comes from solely the fact that Wyndle, Lift's spren considered bonding with Ym, that means these two orders are very close. Learned and giving, the attributes of a Truthwatcher are also there in Kaladin because he trains bridge four and thirteen in Spears, how to make formations and fight. Also like.
Dustbringer- As a guard of Dalinar and Elhokar Kholin, an attribute shared by Herald Chanarach herself, patron Herald of Dustbringers. Guarded the Kholins, never failed, even against Moash and Szeth in different occasions.
Elsecaller- Never fought empty or cold, never got consumed by the Thrill, thinks before action and respects his opponents. He is wise and careful, a trait loved very much by an inkspren.
