Photoshop Assignment

This is a personal project. I need a photo that was partially photoshopped already finished by editing the area between the two people in the photo and fixing the hair so that it looks more authentic and not have it look like it was totally photoshopped. I am enclosing the two original photos that were used to do the photoshop in case it needs to be redone and cannot be fixed. If possible, i would also like to have two or three more new photos created from the photos submitted below of the same two people in the photoshopped picture. I realize this may not be possible. It will involve removing people from pictures and putting another person in. Picture needs to look authentic. The third file is the photoshopped picture. The fourth and fifth files are the original pictures that were used to do the photoshopped one. The 1st, 2nd, pictures 6-9 are ones that can be used to make two or three new photos if they can be done. I realize some photos may not be able to be made into one cohesive picture. If additional photos are needed, I will try to supply them if you can give me some guidance on what is needed.
