1. Where do you get information that
"the Janjaweed is currently fighting against the Sudanese government ? Got a link ?
Th Janjaweed itself is pretty much just a collection of militias, so it isn't even a single entity, but as much as it is we tend to associate it with Husa Milal who we tend to label as the leader. It was he and his militia who signed a memorandum of understanding with anti-government rebels in 2014 and subsequently pledged to fight the Sudanese government. From the UN Sponsored News agency that reports on Darfur:
Sudan SPLM-N Musa Hilal s Revolutionary Council sign MuO Radio Dabanga
And I would ask you where you got info that the Jangaweed was initially armed by Libya, but it is not a very important point.
Darfur: A Long Road to Disaster by Robert O. Collins
It was part of Gaddafi's attempt to create a larger Arab unity state by absorbing Chad and Sudan. His efforts didn't go so well so he stationed his Islamic legion in Darfur and flooded the region with automatic weapons to try to push his claims in both countries through support of rebel groups.
2. Are you saying that the Dinka tribe is NOT the largest ethic group in Sudan ? If so, upon what do you base that ? Link ?
I am saying that yes. The Dinka are not the largest ethnic group in Sudan. I say this because most do not live in the country of Sudan. Most live in the different country of South Sudan where they make up about 15% of the population. It is in South Sudan that they are the largest single ethnic group. They are also not a single tribe as you seem to think they are. The largest ethnic group in the country of Sudan are Arabs (by far). At no point in the history of the region were Dinka the majority.

Or you could simply check the CIA World Fact Book which lists Sudanese Arabs as 70% of Sudan's ethnic population:
The World Factbook
3. Why did you think that the people attacked by the Jangaweed are are primarily Muslim? Looks like YOU are who got this wrong. The people attacked were NOT primarily Muslim. They were Black Africans of the SLA and JEM, who are of members of the African tribes from which the rebel armies draw their strength—the Zaghawa, Masalit, and Fur tribes (not Muslims). The Muslims were the Arab Sudanese govt who armd the Jangaweed and even conducted airstrikes for them prior to their raids against the SLA and JEM.
Black Africans can be Muslims too. The JEM is overwhelmingly composed of Muslims. The Fur, the Zaghawa, and the Masalit are all majority Muslim ethnic groups within the Darfur region. They all have historically been ruled by pretty sultanates.
