見失う（みうしなう） means 'to lose sight of (someone/something visible).' Option 4, 'よそ見をしながら歩いていたから、友達を見失ってしまった' (I was walking while looking away, so I lost sight of my friend), is the correct usage: physically losing visual track of a person you were following or watching.

• 1'相手チームのわずかなすきを見失わず、点を取った' tries to use 見失う for 'not missing an opportunity.' The correct word is 見逃（みのが）す: すきを見逃さず. 見失う is about losing sight of something visible, not failing to catch a chance.
• 2'間違いを見失っていた' tries to use 見失う for 'overlooking errors.' The correct word is 見落（みお）とす. You 見落とす a mistake (fail to notice it); you don't 見失う it.
• 3'最後まで私たちを見失わずに指導してくれた' tries to use 見失う for 'not abandoning / not giving up on.' The correct word is 見捨（みす）てる: 見捨てずに. 見失う is about losing visual sight, not about abandoning someone.

• 見失みうしなう — to lose sight of (someone/something one was watching or following)

「身につける（みにつける）」means 'to acquire / master (knowledge, skills, etc.).' The sentence means 'I want to study hard at this school and acquire knowledge and skills.' 知識や技術を身につける is a very common collocation meaning to internalize/master knowledge and skills, and the volitional form 身につけたい (want to acquire) fits perfectly.

• 2「気に入る（きにいる）」means 'to like / be pleased with (something).' You do not 'want to like' knowledge and skills in this context; the goal is to acquire them, not to be fond of them.
• 3「押し込む（おしこむ）」means 'to push in / stuff in / cram.' Knowledge and skills are not 'stuffed in'; this is physically forceful and unnatural for learning.
• 4「取りあげる（とりあげる）」means 'to take away / confiscate / pick up.' This would mean wanting to take knowledge and skills away from someone, which is the opposite of the intended meaning.

• 身みにつける — to acquire, master (knowledge, skills)

• 押し込む（おしこむ） — to push in, stuff in, cram
• 取とりあげる — to take away, confiscate
