hey mate first of all you dont want to go and do to much weight lifting..only because u are allmost 15 and at your age you could do more damage to your muscle then good.. at your age your muscle wouldent be developed properly yet and if you go and do a lot of weights you will most proberly damage them more then build them..in saying that it dosent mean u cant do anything at all.if u go for a run every day and drink lots of water and eat healthy u will loose that 5 pounds.with the body weight just think with ya head YOU know what food is good and what food is bad(fast food).stay away from the fatty foods and the best thing to drink is WATER and its free.also a good thing would be join some sort of sporting team u will make friends have fun and if u are running then u are gunna loose weight.there are a lot of plans that you can find on the net BUT they might not be for you.the best thing is go to a gym get a personal trainer for the day and explain to them what your goals are and what equipment u have to work with and they will set a plan perfect for you.to do at homego for a run or walk every day for like 20-30 minsand most of all what ever you do make sure you stick at it and u will see results.good luck mate
