They might have a mild fondness for Udyr, due to his spiritualism and deep connection to the world. I also see the possibility of Udyr probably joking around with Kindred with animal forms, but that's less than likely to happen. Due to their nature of appearance changing, Udyr might certainly revere the Eternal Hunters, as a spiritualist would often have no qualms with death.
Bard, however, they might not really have any relationship with. Bard simply preserves the balance of the world through (almost) subtle interaction with the world to stop great cataclysmic events from happening. Kindred however are spirits whose existence is invested in deliverance and finality. They might cross paths, but I doubt they'd ever speak; their presence is simply business.
