Ecommerce Photo Editing

Hi, I have around 60 pictures, I need edited for my ecommerce site. The pictures were taken in a white light box. I don't want to remove the background entirely, I would just like the photos lightened and brightened. I also need some help standardizing the size of the products across all the different images. Right now, some pictures show up as small and others quite large on my site. Open to suggestions but experience with ecommerce photo editing is a must! Please find samples of the original pictures below.
