You cannot, in general, copy the exact same feature behavior from one program into another. Tinkering with settings can sometimes lead to a similar result, but not in this case!
InDesign's justification algorithm is influenced by both Donald Knuth's "optimal spacing" as implemented in TeX, and Hermann Zapf's hz-program. It finds the optimal line breaking points in a paragraph within the constraints set by the user (justified or not; hyphenated or not; length of hyphenated words; number of consecutive hyphens; desired letter and word spacing, and glyph scaling, and the amount of divergence allowed; literally hundreds more parameters). The exact algorithm is patented by Adobe.
It's kind of optimistic to think you only need to adjust some parameters in Word to achieve a similar quality, if only because it does not depend solely on settings but there is a fair amount of program code needed as well.
.. in Opposite writing hundred pages in InDesign will hurt your brain.
If you have both programs, use both! Word is a good tool to write text in but has lousy formatting. Writing text directly in InDesign is a pain, but it has superior formatting. So use Word to only process your text, and InDesign to do the final layout.
.. Unfortunately InDesign and Word only communicate using "RTF" insttead of DOCx
Not true. InDesign has been able to import both DOC and DOCX files for a while now. The latest version has no particular problems with importing DOCX generated by the latest versions of Word.
The underlying problem in using InDesign may be because InDesign is professional-level software, and not really aimed at the casual beginner. Point in case: you don't have to create text frames for each separate page, you can enable Autoflow for that. But as said above, don't write in InDesign. Write all in Word, proofread and correct it, and only then import it into InDesign for final lay-out. And when finally importing your text, you can choose to have InDesign create as many pages as necessary.
