So. I'm just going down your role list and see if I have anything to match :D
Jeweler: metallic colors, filigree would be a nice touch
This pair isn't metallic colored at all but the lore would fit. The lady skydancer is the daugther of a travelling jewelier and once made a necklace that mesmerized her beloved. It would make sense for one of their children to inherit the skillset.
Riverside Magic
100% Skydancer
Thief: ice or shadow flight? triple black range?
They don't have lore yet but I can easily imagine them as mischievous little troublemakers. They will breed in wind. Maybe a spiral that robs a lair within a few seconds or a fae that can sneek in unseen because of its size.
Haunted Winds
70% Fae / 30% Spiral
Historian: earth snapper?
Once more a completly different vibe but again, the lore would fit. The little fae was once a tundra from an ancient tribe and tried to discover all the mysteries revolving around these strange tundras. The curiosity could easily be passed down.
Deepest Trench
70%Fae/ 30% Spiral
Nursery dragon: probably female, pastel colors
Not pastels but they are going to breed in nature and I find the naturetheme and the soft tones that come of that pair very fitting. The parents don't have lore yet though.
Grassland Dreamers
50% Imperial / 50% Nocturne
Witch: probably green primary, maybe a noc
These two would make great witches
Healer: no thoughts
Could fit. Could not
Golden Curse
90% Ridgeback / 10% Imperial
Painted Clouds
100% Skydancer
Seer: Must be waterflight/
Fishers: water themed
Female pearcatchers always have a mystic-magic vibe... They could also make great fishers though
Reef Lizards
50% Ridgeback / 50% Pearlcatcher
For the rest I don't know really but you are more then welcome to check out my hatchery! The perma parents have lore, the probation pairs mostly not but they will got some once they are being promoted :D
