For these kinds of questions you may find a word search or topical index resource helpful, e.g.
From:
https://www.studyquran.org/
https://www.studyquran.org/TopicsIndex.htm
https://www.studyquran.org/WordSearch.htm
You can then read every occurrence of "Ishmael" for example. In this case, quote:
Ishmael, 2:136, 2:140, 3:84, 4:163, 6:86, 14:39, 21:85, 37:102-109, 38:48
and Hagar, 2:158
Note: since the references are taken from a Traditional Islam website there may be some wording issues, but the actual verse references should be accurate.
