Keywords and their synonymes - can I use them THIS way?

Hello Warriorforum!

Situation description:
(my examples are fictitious)

main keyword 1 = small breasts (assuming many searches)
main keyword 2 = tiny breasts (assuming many searches)
Synonym 1 - small chest (assumed average number of searches)
Synonym 2 - no bosom (mean number of search searches)
Synonym 3 - little chest (mean number searches)

With the main keywords I want to create a separate page on the site. But I dont want to do without the synonym keywords that have exactly the same meaning as the main keywords, but less searches. So I want to use these synonym keywords in other topics in my articles.

For example:

Article 1: Does a small chest of a woman really affect her attractiveness?
Article 2: How can small breasts of a woman affect her behaviour?
Article 3: Are there any men who like women with little chest?

Now my questions:
Would Google view these articles as duplicates? Are there any negative interaction? Would my strategy negatively affect the number of visitors to the main page with the main keyword?

Thank you in advance

PS:? Long tail keywords I want to use as well, but they are not the topic here.
