Yokuda

For Yokudan mythology, look to the Reguards. It can be argued that they are both the same and also not the same as the Eight.

Maormer

The Maormer are strictly Lorkhanic/Padomaic Mer. Their king was made from the skin of the Serpent, who is Lorkhan.

Akavir

Well, here there's Tosh-Raka, who is an obvious subgradiant of the Time Dragon, a part of Aka. Given this, it seems possible there are other potential Divines, but we have no information about it at all.

Considerations

Keep in mind that the concept of the Eight Divines is something very old. Both ancient Atmoran and ancient Aldmeri pantheons contained the Eight. It was because of this that the Alessian Order were able to integrate the two religions together to form the Cyrodilic pantheon so well. There's obvious holes and gaps in the Alessian Eight, but it made enough people happy. There are also the Eight Divines as in "heavenly bodies," i.e. the Plane(t)s. It's quite obvious that the Eight are fundamental to the mythic structure of the Aurbis (eight spokes of the Wheel).
