the first one makes me think of one of my student's question. one time we studied a funny Chinese video, there is a sentence “忙不过来”，it is about “过来”。he asked me,is it okay to say “睡不过来”。after I explained what it means, he was so embarrassed, cause his gf is with us. ““照顾不过来””and“忙不过来”，过来 is the same meaning which means the contents is too much to take care,to deal with or to settle

sentence 5，6，7，8 easy！just Verb with direction,➡️⬅️⬇️⬆️

“加起来” [indicating completeness or effectiveness] “存起来”

3.“改过来”[indicating a return to the normal state] come round, eg. 醒过来

2.这一个很简单。“传过来”pass through, “过来”⬅️
