I've heard of adherents to Thor, and his totem (an upside-down hammer) is widely available as jewelry, so there's likely to be some worship of Odin.
Worship of Horus was subsumed into Judeo-Christianity. As we should well know, J-C was formed of a lot of diverse or pagan rituals and feelings. Jehovah is a just a sun god revisited for a newer age.
