How to say "fellow" in Japanese

• やつCommon
  nounCovers 'fellow' as a casual 'guy' or 'chap' in everyday speech; the tone can be dismissive or affectionate depending on context. Usually written in kana alone.
  欠点けってんはあるけれども、彼かれはいい奴やつだ。↗

• 同士どうしJLPT N1approx.Common
  noun, noun (suffix)Covers 'fellow' in the sense of people who share the same status or situation, with a mutual, comrade-like nuance; it points to a shared bond rather than one individual.
  １０代だいの友ともだち同士どうしが徹夜てつやでおしゃべりした。↗

• 仲間なかまJLPT N3approx.Common
  nounCovers 'fellow' as companion, mate, or friend — someone who belongs to the same group as you. Fits talk of teammates, friends, or people on the same side.

• 野郎やろうCommon
  nounA rough 'guy' or 'chap', mainly about men; depending on tone it can be an insult or rough banter, so it does not fit neutral, polite description.
• 輩やからCommon
  nounRarely the right choice for an individual 'fellow': its real senses are a party, set, or clan of people, so reach for it only when 'fellow' means a whole group.

Use 「やつ」 or 野郎 for a casual 'guy' or 'chap', 仲間 for a companion or mate in your group, 同士 for people sharing the same situation, and 輩 only when you mean a whole group of people.
