Work hard, eat well, sleep.

I also sometimes sleep at 10, 12, 3 even at 6. Just make sure you have enough rest.

I started workout on January until now. Gained from 52kg to 69kg. No supplement. Just started using whey last month. Having a partner/spotter is important too.

Don't forget your diet!

u wont go far. protein powder is no magic.

Both simultaneously. You'll notice that by increasing vegetables and complex carbs which contain good amounts of vitamins (e.g. sweet potatoes) which are essential to your well-being, your calorie count is easily maintained.

Yes. Supplement is just for supplementing deficiencies.

Ideal situation would be to stay away from processed food and beverages that you can find on any shelves.

Lightly cook raw foods that are laced with minimal pesticides, ideally organic if you have the money.

Take a whole-foods derived natural vitamin a few times a week.

Exercise diligently. Sleep well and early. Get moderate sunlight everyday. You'll be a healthy man.
