週しゅうN3
週 is the general word for 'week' used in counting or compounds like 週末, while 週間 specifically denotes a duration of one week and is used with numbers like 一週間.

習しゅう慣かんN4
週間 (a period of a week) and 習慣 (a habit or custom) are pronounced identically but have completely unrelated meanings.
一いっ週しゅう間かん
一週間 already includes the number 'one' and means a full week's duration, whereas 週間 alone is just the unit 'week' and needs a number before it (二週間, 三週間) or appears in campaign names like 交通安全週間.
月げっ間かん
週間 denotes a one-week period (or themed campaign) while 月間 denotes a one-month period; the two are easily confused because they share the same grammatical pattern of attaching to nouns.

週 is the noun 'week' itself, while 週間 is the counter suffix used after a number to mean 'a period of X weeks' (e.g., 二週間).

Compound of 週 (しゅう, 'week') and 間 (かん, 'interval, period'). The reading しゅうかん follows standard on'yomi.
