Yes. As a beginner, practice with only these. Start with the 7i. When that is consistant, work on the 5w. Then branch from there: 9i, 5i, 3w.

Using these first, will definatly help with the longer clubs when you start to incorporate them into your bag. You will know it is time to add clubs when you get mad that you should have used a 6i when your 5i went over the green.
