Does hell consist of 7 levels?

In this [website](http://www.myreligionislam.com/detail.asp?Aid=5974) the author of the article claims: Hell consists of seven levels. The torment inflicted in each level is severer than the torment inflicted in the level above it. (Faraid-ul-Fawaid) - The first level: Its name is Jahannam, which is the least severe in torment. Sinful Muslims will be inflicted torment there. - The second level: Its name is Sa'ir, whose fire and torment is severer. Jews will suffer torment there. - The third level: Its name is Saqar, which is much severer in torment. Christians will suffer torment there. - The fourth level: Its name is Jahim, where those who worship the Sun and stars will be inflicted torment. - The fifth level: Its name is Hutamah, where Zoroastrians, Buddhists, and Brahmans will be inflicted torment. - The sixth level: Its name is Lazy, where atheists, polytheists, and heathens will be inflicted torment. - The seventh level: Its name is Hawiyah, which is the severest in torment. Hypocrites and apostates (murtads) will be inflicted torment there. Are those levels supported by evidence from the Quran or Sunnah? And also isn't Christianity and Judaism just Islam, so why would they go to Hell according to this article?
