@evani,sorry for the long wait. Had an exam to write.
1)no,we have seen that a person with a borrowed eye can use it just as good as one who awoke it,like danzo,kakashi,ao,madara too with obito's ms.
Madara as the original owner would know far more about the rinnegan's abilities than obito or nagato and not only that,he would also be able to use his susanoo with rinnegan active. Therefore the amount of techs he would use with his rinnegan will be more than either. The power aspect comes from the users themselves,if one rinnegan user has more power than another,his rinnegan techs will surpass the other. Obito also said 'eyes' get their full power when together,which means he meant all dojutsu. Thus being the original owner dosent give u the full power,but having both eyes. Not only an sm user which would boost his power,but a juubi jin,clearly his use of the rinnegan would by far surpass what a base nagato can do,give nagato sm juubi and can do the same.
Nagato can use the 6 paths just like hago,he can use CT just like hago,he can use gedo just like madara,he can use yinyang just like hago. He can use abiliies that these 2 have shown,only difference is one is a sage juubi jin,the other is a son of kaguya and also a juubi jin,they have far more power to put into their techs. Madara used his rinnegan on that level because he was a juubi jin and sage.
2) shockwaves are passive,created by relative motion of the sword close to the ground,it is not somet

madara's aim was to cut the wood arms,the wave followed his slash,hitting mountains on every direction,if your slash is good enough,a wave is made,if not you get nothing.
Liger bomb completely broke a rib of sasuke's susanoo,it wasnt even meant for ribcage susanoo,just base sasuke.
Indra had ms when he used ps.
3) sasuke himself shot the flames,so he saw them get absorbed,i am pretty sure ninjutsu is what nardo meant,as gen and tau cant be absorbed.
Sasuke wanted madara dead badly,it showed in his face and his words,if he could he would have. He didnt use ps against obito from the start cuz he hadnt unloked it then,he went through stages,first making a legged susanoo,then ps,just like in the kage summit when he unlocked ribcage,then v2,then v3 against danzo,then v4 against kakashi,and we have seen that when sasuke unlocks a new form he frequently uses that form. He wanted madara dead badly,you think he would skip ps for henjutsu if he could?,even when madara was easily dodging his blows?.
Edos cant attack eachother,nagato could counter cuz he was an edo.
4) madara made the chain,thus he wasnt affected,and the chains werent suppressing his chakra either,9 bijuus were helpless there,and each bijuu has the offensive power of madara's ps as he stated himself. Unless sasuke has an attack greater than hago's ct,he isnt doing anything.
5) jiraiya isnt a sensor in base,nor could he sense him in sm,so thats irelevant,ma retorted to using her tounge rather than sensing him,naruto couldnt sense him
in your scan ma herself said the barrier was useless.
Animal pth could see through the animal while inside

which would be impossible seeing s the rinnegan nor sharingan can see through chakra,which is why hidden mist blinds them,and the reason why deva couldnt see naruto inside bunta
if he could look through the chamelion,
then it has no bisible chakra to see
nagato was a snsnor,not pain
