how do I add multiple pics into a background without losing quality

Hi Guys...Need help pls. I have a background picture. Now I want to add the 4 players into the background and of course with each single picture, there is already their own background..How do I this? Problem is when I save a picture of a player and try to drop it into the background picture, its very small and when I use the transform tool, I can scale it but its blurry. How do I add pics without having a blur effect. Basically I would like to create an ad like this but dont know how to...pls help
