How to correct two slightly blurred faces in the center of a photo?

Hi Everyone,

I really need all of  your help in quickly finding a solution to my problem. Yesterday evening, I took pictures of the entire graduation of our City's alternative high school. It is my way of paying it forward for all of the help the school gave my oldest son, Ian. He graduated from the school 7 years ago. In 2020, Ian will be receiving his Masters in Economics.

During the graduation rehearsal earlier in the morning, I suggested to the principal to have all 60 students upon being handed their diplomas to turn and face the crowd for 5 -10 seconds in order for their familes and friends to take a great picture. In addition, more importantly, I would be able to get a great picture of each student from my seat in the bleachers directly in front of the stage.

Equipment: Nikon 7000 camera with a 55 - 300 mm lens using a monopod.

When I started editing the pictures using Photoshop Elements 2018, I found on 15 of the straight on pictures I took that the faces of the students and school officials in the center of theses pictures seems to be slightly out of focus and lighter than that rest of the picture. In contrast, all of the other people in the picture in the back and on the sides look normal.

This is my problem - I need to find a way using Photoshop Elements 2018 to correct the faces of the students and the school officials on these 15 pictures or the pictures of those 15 students will not be included in the final picture link. If I do not include these 15 pictures in the final link, I will feel terrible.

PLEASE HELP ME.

Thank you all so much for any help you can give me.

Peace and Hope
