Approximately 1 to 4% of non-African modern human DNA is shared with Neanderthals. dont it affect the theory of only one mother of all of us?
The evolutionary history of the modern human species is complex, more so than we predicted 10 or 20 years ago. I don't know your scientific background, but here is recent review article on the subject.

It seems mtdna technique is also looks vague. Since many interpretations are coming out. Who is the authority which will declare MRE or RAO models are incorrect. Till date I didnt found a clear declaration about RAO model rejection.
No, all Homo sapiens came from Africa, just that in the movement in other continents they mated with other hominins species acquiring some portions of their DNA. Nonetheless, it has become quite clear now that the portion of Neandertal DNA is very variable and also the position in the DNA helix varies, for every non-subsaharian African person. Furthermore, it has been showed that the portion of "archaic" DNA had gradually reduced during time, implying it wasn't good in an evolutionary term, the portion we have retained are almost all related to protection and adaptation to environment and pathologies. Thus the archaic DNA portion in modern humans doesn't affect the theory of the solely african origin of our species.
The statement ` mated with other homo species....` itself ruled out the possibility of only one mother of all of us 200000 yrs before.
as for now Homo sapiens is a species, not regarding the presence of archaic DNA in non-subsaharian African people. so if you're question was if all modern humans have , evolutionary speaking, originated in Africa, the answer is yes. If you want to track all the nowadays modern human DNA to a single woman of 200'000 ky BP, I don't think you could achieve such a result.
True, right now I am not putting any question mark on RAO.
But the statement '' Using mtDNA scientist regressed back... back... and discovered that 200000 yrs back there is a only one mother of all of us. She only given birth to Homo sapiens (i.e. all of us) etc." looks false if we see other researches which claims ` Homo sapiens mated with other homo species....`
I still can't see your point. Is quite obvious that the mithocondrial Eva is just a figure for saying that all modern humans come from a quite little group that have originated, likely, in East Africa. The fact that modern humans during their migration met other hominins (Neandertal and Denisovians) and the outcome was a few percentage of archaic DNA doesn't affect at all what Homo sapiens is, beacause genetically and evolutionary we're different from Neandertals and Denisovans.
you answered it in reply 1 and 2, and diluted in third one. no problem but you said correct and I agree with answer.
In total you said,
1) there was group of females who are responsible for sapiens species, not a single women
2) few percents of today's total population may be out come of cross breed of sapiens with Neandertal /Denisovians.
is it fine?
Now next question In line
1) how much sapiens DNA similar with chimpanzees ?
And
2) how much Neandertal /Denisovians DNA similar with chimpanzees?
Is this paper putting question mark on RAO model?

Is it the rejection of RAO model?
