How to say "together" in Japanese

• 共々ともどもCommon
  adverbCovers 'together' in the sense of being in someone's company. For the everyday 'do X together' it is seldom the word you want — that is 一緒に's role.
  私は彼かれともどもその企業きぎょうに参加さんかした。↗

  I share with him in the enterprise.
• ともにJLPT N3approx.Common
  adverbCovers 'together; jointly' — two or more people or sides acting as one or sharing an aim or experience. It is normally written in kana.
  私と共ともに来きてくれませんか。↗

  Would you mind coming with me?
• 一緒にいっしょにCommon
  adverbThe usual, all-purpose word for 'together (with)': being or doing something with someone, such as going, eating or working together. If you simply mean 'with someone', this is it.
• 相まってあいまってCommon
  adverbNot about people being together in one place: it says that one thing, coupled with another, produces a result — one factor combining with a second to bring something about.
  性能せいのうのよさとデザインの優美ゆうびさが両々りょうりょう相あいまって本ほん機種きしゅの声価せいかを高たかめてきた。↗

  The high performance and the elegant design of this model have combined to give it a high reputation.
• 互いにたがいにCommon
  adverbCovers 'together' only in the reciprocal sense: two parties doing something to or with each other — 'mutually'. For plain 'together with someone' it is not the word you want.
  私達わたしたちは互たがいに依存いぞんしあっている。↗

  We are dependent on each other.

Choose 「一緒に」 for being or doing something with someone, 「ともに」 for joint action or shared aims, 「互いに」 for mutual 'each other' action, 「相まって」 for one factor coupled with another, and treat 共々 as a marginal 'in company' option.
