Yes, you can upgrade old ones or even start them from scratch. Personally I have my eye on Sally  the Cat which was the first one and before I started playing.

And it looks like each has a slightly different reward for completion. The hedgehog gets you 180 energy, Magesterium, Tool kit chest and 5 winding keys and diagrams. Sparky and the reindeer and Sally gets 3, 60 energy, 1 120 energy, 1 600 energy a SOV and Tool kit. Lucky is 300 enrgy, 600 energy, SOV Tool  kit, dragon fly + cotton. Fox is 35 E, 600 E, Magesterium, Tool Kit and 2 Dragon fly +cotton. Raccoon is 600 E, Ring of Runes (30% collections for 2 hours) Magesterium and Tool kit. Squirrel is 300 E, 60 E, Magesterium and tool kit and Owl is 600 E  Magesterium, Tool Kit and 2 Dragon fly +cotton
