What should i do to make breast larger without getting boob job?

Not many options: The usual ways are 1. Breast implants surgery 2. Fat injections in to the breasts other ways --- (minimal amounts ?) 1. Suction devices applied to the breasts 2. Wait gain (?).

Not much: You can gain weight, but that is not generally a healthy way to increase size. Suction devices only temporarily increase size. Hormonal treatments are not safe. Fat injections require liposuction to harvest the fat, which is surgery.

Sorry...: Currently, there isn't a good non-surgical method. The brava, a suction-based device for breast enlargement, had disappointing results when used by itself. There are no creams, pills or other methods that work.
