brothers

Here "brothers" means fellow Christians, including both men and women.

The pronouns "you" and "your" refer to the Gentile believers.

so that you may not be wise in your own thinking

Paul does not want the Gentile believers to think they are wiser than the Jewish unbelievers. Alternate translation: "so that you will not think you are wiser than you are" (See: rc://en/ta/man/translate/figs-explicit)

A partial hardening has come upon Israel

This is the mystery that Paul referred to earlier in the sentence. This can be made a explicit. "A partial hardening" is a metaphor for many of the people remaining stubborn. Paul said this because some of the Jews stubbornly refused to trust Jesus. Alternate translation: "This mystery is that a partial hardening has come upon Israel" or "Many people of Israel remain stubborn" (See: rc://en/ta/man/translate/figs-explicit and rc://en/ta/man/translate/figs-metaphor)

until the full number of the Gentiles

Here "full number" means the amount determined by God. It does not mean all Gentiles. Alternate translation: "until the number of Gentiles determined by God" (See: rc://en/ta/man/translate/figs-explicit)

comes in

This is a metaphor meaning to be saved or to become a Christian. Alternate translation: "is saved" or "believes in Christ" (See: rc://en/ta/man/translate/figs-metaphor)
