Now that I've read a bit about Zoroastrianism up to the 300 AD, I can answer this now.

>I know virtually nothing about Zoro as a religion. How likely that Zoro touched Palestine?
I'm not sure what you're asking, but for me it's become certain that it influenced Christianity. I suppose a Christian might try to argue that their religion is the pure one that influenced the other while absorbing nothing, but that doesn't seem to be the consensus by objective academics.
>Why would the Apostles copy Zoro? Wouldn't that make them lose credibility?
I don't think credibility from exclusivity was a concern back then, because Judaism already was heavily drawing from Zoroastrian teachings without worrying about the foreignness. Syncretism was in vogue, and excluding foreign mysticism based on origin was less of a thing before the canon was established. They probably thought Zoroaster was an inspired teacher or prophet, just as much as their own from Palestine, and there are several passages in Talmudic sources that explicitly reference his religion, and cosmological framework with archangels of light and darkness that engage in a final battle, sometimes even complete with Persian loan words.
Christianity was also already drawing from Zoroastrianism from the book of Daniel, which included Iraninan loan words, and a Zoroastrian metaphor about metals as empires which you see mirrored in Daniel's interpretation of Nebecenezar's dream.
Zoroastrianism also imparted the idea of hell as a place of punishment that replaced Shedol, the Jewish afterlife which was a place of shades. In fact, the idea of cold and hot hells in certain Buddhist scriptures might be inspired by Zoroastrianism.
>What if Zoro is talking about the same stuff using other names?
There were indeed multiple Zarathrustias over the years (Persian name, the Zoroastria word is a greek rendition of it). Different speakers put different words in the mouth of Zarathrustia who was respected as a sage of the East for thousands of years. The Greeks did it too, which is why Greeks associated him with astrology. Rather than to release and promote new teachings without a name, people often said wise Oriental Zarathrustia said it so people would listen.
Of course, you don't have to believe any of this, but this is what I have read.
