Those are kind of hard questions. Because it's a little complicated. 1 Yarou=野郎（やろう）　 It's a modern word(compare with Onore). Most of the case it is used as exclamations of anger to a man. like motherf○cker, son of a bi...etc. But it simply can be used as a guy once in a while too. 2 Sama=様（さま） It's one of honorifics. 王様（おうさま King）、神様（かみさま God）、お客様（おきゃくさまCustomer） etc... But in terms of 貴様（きさま You）, it doesn't have the meaning as a honorifics in nowadays. It's similar to 野郎. 3 Onore=己（おのれ） It's an archaic word. 己 itself means "myself". But it can be used against the opponent. In that case the meaning is similar to 野郎. In a period drama, it seems to be used as myself or an exclamation both ways.
