睡すい眠みん不ぶ足そくN3
睡眠不足 is the more formal, clinical term for sleep deprivation, while 寝不足 is the everyday word people use in casual conversation.
不ふ眠みんN1
寝不足 is a casual, everyday term for lack of sleep or feeling sleepy from not sleeping enough, whereas 不眠 sounds more formal or clinical and can imply an inability to sleep at all.
不ふ眠みん症しょう
寝不足 is a casual, everyday word for not having slept enough, without the clinical weight that 不眠症 carries.

不ふ眠みんN1
不眠 means being unable to sleep (as in insomnia), whereas 寝不足 means simply not having slept enough time, regardless of the cause.
寝ね坊ぼうN4
寝坊 means oversleeping or waking up late, which is the opposite situation from 寝不足's lack of sleep, though both share the kanji 寝 and are easy to mix up.

Compound of 寝 (ne, 'sleep') and 不足 (fusoku, 'insufficiency'). The reading ねぶそく reflects rendaku voicing of ふ to ぶ.
