I have got a US immigration visa (temporary, based on EB-5) stamped on my passport from the US embassy. After this, I am planning to travel to US soon. After landing in the US, after one week, can I (along with my kid, derivative) travel out of of the US for 3 months, without getting a hard copy of my green card (as it will take more time) or do I need to apply for advance parole?

The stamp on your passport serves as proof of your green card status, so you can freely travel with the stamp.
If immigrant visa still has validity and/or you have valid I-551 stamp and return before its expiration, you should be fine for travel.
If you have a valid immigrant visa stamp in your passport, this will be sufficient for you to reenter after a three-month absence. You cannot get advance parole since that is not for permanent residents.
