You need to pick up the book 23 Minutes in Hell, its very good. The book tells you what it's like in hell and i would recommend non-believers to read it!
1.Why should Satan and the fallen angels (demons) get rewarded?
No one is saying they are getting rewarded. Demons and Satan himself will be torture for eternaty.
2. God can neverd be punished, He is God. God can be at all places at all time.
I do not feel like getting into a debate about the existence of hell here since the topic has been discussed multiple times in this site: http://www.allaboutgod.net/forum/topics/how-can-a-good-god-send-peo...
but would like to point out that this site does believe the historical and biblical account of Hell, according to the scriptures and not what the web sites that you often referred people to subcribes to.
I found an article on the page you get a lot of your information from (If i am mistaken do please feel free to correct me.): http://www.humyo.com/!#/9538789/Other%20events%20and%20concerns/6e%20Prophecy%20theories%20and%20fulfillments/
stating that people will not be torture in hell etc... Is that what you believe?
