Talos is most definitely a god. Tiber Septim's armor was used in a ritual by Martin which required "Divine Blood" and it was a Daedric Ritual so that means the Daedra acknowledge Talos as a Divine. There is also Wulf, an avatar of Talos, that can be met in Morrowind.

All the Daedric Princes obviously exist.

Kynareth has a few quests that involve her, and she was personally acknowledged by Paarthurnax. So she very real.
