「外人」 is colloquial for a foreigner or an outsider, with a distancing feel that can be rude face to face. The default is 「外国人」 — neutral, standard and safe in any setting. For someone outside a group or area, 「よそ者」 fits better. Literary words like 異国人, 異邦人 and エトランゼ are seldom heard in daily conversation, while 異人 and 唐人 are historical; the discriminatory 夷, 夷人, 夷狄 and the slurs 「毛唐」 and 「毛唐人」 must be avoided. For one's own circle, the opposites are 「身内」 and 「内輪」.
