Photo mixing / merging

I used a same background and same exposure and did 4 shots with my daughter in four different places in the frame. I want to create a photo which need to look like a group photo with 4 subjects with all the subjects being my daughter. Can any one list out the steps in photoshop?
Thanks

no sure I understand but it sounds like you want to have her in one image, 4 times?What I think you need to do is crop out her image from all 4 shoots maybe just 3 and here her in 4 different layers ........ only guessing here
