Asalaamu Alaykum

My questions are these:

In Quran 19:33 Jesus(PBUH) says
And peace is on me the day I was born and the day I will die and the day I am raised alive."
But Jesus never died and he never will die when he comes on the day of judgement,but how come he said peace be upon me the day I will die?
And other thing is a friend of mine asked me about Quran 2:62
Indeed, those who believed and those who were Jews or Christians or Sabeans [before Prophet Muhammad] - those [among them] who believed in Allah and the Last Day and did righteousness - will have their reward with their Lord, and no fear will there be concerning them, nor will they grieve.
And in 3:85 it says
And whoever desires other than Islam as religion - never will it be accepted from him, and he, in the Hereafter, will be among the losers.
He asked me is this a contradiction I told him there is no contradictions in Quran but he said,in 2:62 it says I can be a Jew or Christian and be safe but in 3:85 it says only Islam is accepted by God.could you elaborate more on this and help me with this and explain so I can make it clear to him that it's not a contradictions

And finally

Quran 70:4 it says
The angels and the Spirit will ascend to Him during a Day the extent of which is fifty thousand years.
And in 32:5 it says
He arranges [each] matter from the heaven to the earth; then it will ascend to Him in a Day, the extent of which is a thousand years of those which you count.
The extent is a thousand years or 50 thousand years?
I would like you to explain this to me,as a muslim I believe there is no contradiction in Quran but I am confused about this.
Please I really need your help with this
