Sannin Lose, C & D beat tsunade every time, tsunade is only strong in taijutsu and c & d can be long - short range fighters, you are forgetting that darui also has storm element and techs like lazer circus and such, so tsunade dies.
if jiriya starts in sage mode then i think A loses by a tad, but if not jiriya gets beaten, but darui or c might end up helping if j-man goes into sage mode.
B vs oro bee would screw tobirama because lightning is weak to water, but would have a hard time against hirashima and darui or c would most likely intervene to help Bee then they would have oro beat.
In the end though i think the sannin + 1st and 2nd hokages Lose.
