Is it ok or normal for both nipples not to be completely flat after gynecomastia surgery? (photos)

It is too early to evaluate your final result. But you should certainly communicate your concerns to your plastic surgeons office. They can reassure you if they believe things are progessing normally. 

Thank you for your question and photos.  As you are only one week post-op, my assumption would be that it is indeed swelling.  You may also have had some residual scar tissue from the first liposuction, and because of that, the tissue may take a little longer to flatten out.  I recommend that my patients wear a tight compression vest under their shirt for at least four weeks after surgery, but follow the instructions of your PS.  Best wishes!
