How to say "participant" in Japanese

• メンバーJLPT N3approx.Common
  nounPrimarily 'member' — a person belonging to a group, team, or organization. It can also suggest an attendee, and in sports it is used for a team lineup, so it only loosely covers 'participant'.
  ボーリングに行いくなら私をメンバーからはずしておいて。↗

  Count me out if you go bowling.
• 参加者さんかしゃCommon
  nounThe most direct word for 'participant': someone who takes part in an event, activity, or competition. It also covers entrants, players, and competitors, making it the safe default choice for most senses.
  その部屋へやは参加者さんかしゃの熱気ねっきでムンムンしていた。↗

  The air in that room was thick with the enthusiasm of the participants.
• 出席者しゅっせきしゃCommon
  nounUsed for 'attendee' or a person present at a meeting, class, or gathering. Choose it when 'participant' really means someone physically in attendance rather than someone actively taking part in the proceedings.
  会かいの出席者しゅっせきしゃは多おおかった。↗

  The meeting was well attended.
• 演者えんじゃCommon
  nounMeaning 'performer' or 'actor', this word is used for a participant in a TV show or TV panel. Outside that broadcast context it is seldom the word you want for 'participant'.

Use 参加者 for people taking part in an activity, 出席者 for people physically present at a meeting, 「メンバー」 for members of a group or team lineup, and 演者 for TV performers or panellists.
