adding and deleting someone to a couple of photos. Changing the color of a shirt.

Picture Number 1: I need the man in the blue and white stripped shirt to be added to the photo with the lady and the baby. I'd like for his back arm to show as much as possible behind the baby. I'd like the lady moved in closer to the baby, if possible. And, the right thigh on the lady trimmed on the hamstring closest to the ground. Picture Number 2: I'd like the man in the blue and white stripped shirt to replace the old man in the picture with the lady and the baby, and for the blue and white stripped shirt to be made a solid color. If facial features can be slightly changed to look different from Picture Number 1, that would be great.
