I'm sure you're already aware you can't use A - S ranks so just to make sure you know you can't use them.
Darkness cry - Approved.
Soul reversal - Denied, because most Anbu / Jonin learn more then one A ranked jutsu, and Kages learn tons of them, so pretty much anyone in the ninja world would be able to suck someones life force.
Shield of Oblivian - Denied, first of all you would have had to have a character who already specializes in Necromancy to be able to do anything with the dead yet alone make an entire barrier with dead souls. Plus, even if it did you can't have a B ranking jutsu cancle out every single other type of non S - Rank jutsu, espessicially because A ranks are usally better then B ranks.
Dark Eclipse - Denied, No ninja can control the moon, espessicially not a genin, and even if none of those applied you wouldn't be able to see because if the moon covered up the entire sun there would be no light what so ever.
Demi Bullet - Accepted as long as you take out the part of it always doing a fixed amount of damage.
Hells limbo - Denied unless to make it fair you automaticly take any damage that the body recieves E.G. you control Kakashi ( unlikely ) and you sit there while a kunai hits you in the arm, Kakashi AND you take damage.
Soul plunge - Explain better I can't really understand what your getting at.
