At what age can my daughter have strawberries and other foods?

My daughter is 6 months and has been having gerber stage 1 food for 2 months is she now old enough to start stage 2 gerber food? The difference between stage 1 and 2 is the thinckness (which I know she CAN handle) and the ingredients.... strawberries, mango, pinapple, blackberries, blueberries, corn, cherries, and stuff like that... so what I need to know is can she have those ingredients?
