As far as Amazonesses go, I believe there isn't that much actual information on them in-universe either. I can summarize what I know personally, if that is of any help.

1. Amazonesses are a sub-race of humans who are all female. They can mate with [b]any[/b] other race, but will only ever give birth to new Amazonesses.

2. They have their own language that is unique from the common tongue spoken in Orarior and otherwise.

3. They have their own village outside and away from Orario, where they go to give birth to their daugher(s) and grow up. Adolscent Amazonesses usually leave the village to go in search of a partner - or other reasons, as with Tione and Tiona.

4. [b]This is unreliable and unconfirmed information:[/b] It seems that the Kali Familia consists almost entirely of Amazonsses and it's possible they have their own village. Kali makes her Children fight each other in an Arena in order to make them grow stronger. Some Amazonesses resent this lifestyle - as with Tione and tiona.

5. Amazonesses [i]always[/i] have dark skin, but not necessarily dark hair. There are those with blonde and white hair, which leads me to believe they can have almost any hair color really.

6. Although Humans are in-world considerd to be the weakest race, Amazonesses are not lumped in the same group. This gives rise to the idea taht the Amazoness are somehow physically superior to regular humans. This may also explain why they have such dominant genes with which to override any other races' and only give birth to more Amazons.

Again, this is partly wiki-info and partly info I've either raed somewhere or conjectured together. Do not take anything from point 4 and onwards as clear, cemented fact though.
