There are a lot of mountains in Samoa, but I don't know what you mean by "main". The highest mountain in Samoa is Mount Silisili.
I am not sure what the question is here. In case you mean, "Are you a Samoan?", then it is, "O oe o se Samoa?"
What sort of group do you mean?
The brave, the strong, the warrior or the hero
