• Synonym行列ぎょうれつNeutralA queue of people waiting or a procession, as in 「行列のできる店」; it need not be an organized formation like 「隊列」.
• Synonym隊伍たいごWrittenFormal, for an orderly formed body, mostly military, as in 「隊伍を組む」.
• Synonym列伍WrittenA written, formal term for ranks or a formation, now very rare; say 「隊列」 instead.
• RelatedラインNeutralLoanword for a line or row, also a boundary or route; unlike 「隊列」 it does not specifically mean a formed-up body of troops.
• Related列れつNeutralThe most general word for a line or row, as in 「列に並ぶ」; it lacks 「隊列」's emphasis on an organized formation.
• Antonym散乱さんらんNeutralScattered and in disarray; the opposite of the neat, orderly arrangement 「隊列」 implies.

For everyday lines and queues, 「列」 and 「行列」 are the default; use 「隊列」 for an organized body such as troops or a parade, as in 「隊列を組んで行進する」. 「散乱」 is the opposite, for things scattered in disorder.
