Diet on a budget

Here's a diet that goes along with your workout regime.

I’m 22 years old, I weigh 58 kg and my height is 5’8”. I’ve recently joined a gym with the intention of building muscles. Is it possible to do that within six months? Please suggest a diet that goes along with my workout regime. I cannot afford costly products.

I’m a 17-year-old boy and have excess fat around my chest. I walk on the treadmill at the speed of 5.5 km/hour for 20-25 minutes and do 15-20 crunches daily. I’ve been doing this for the past month and have found satisfactory results, but is this enough? Being in class XII, I can only devote about one hour for exercise every day. Also, please tell me what foods/fruits are good for my skin; I have a fair complexion but my neck and face are dark.
