Hi Coolbit, we would love to answer the questions 
1
This sentence means that, when Prediction proposal A is in the ‘end’ status, which means ‘waiting for result’, and users can not predict in this Prediction proposal A since the voting period has ended and we are waiting for the governance node to upload the results. But people can initiate multiple prediction proposals (active) at the same time.
2 There is a staking system in X Protocol, where people can stake certain amount of POT (governance token) to become a node.
When the result generation time set during the prediction topic creation comes, the
prediction result is uploaded by the governance node through the oracle and should be
accepted by the trial of all users during the result publicity period. In the future, we will
develop a graphical operation interface for non-technical personnel to use the oracle to
upload results. The result publicity period is initially set to 3 days, and it can be revised
through the community voting in the future.
Users can report wrong nodes that upload results that are inconsistent with actual events.
When reporting, it is necessary to stake more than twice of the staked amount of
governance tokens of the reported node. If the reporter cannot raise that many tokens
by himself, he can also initiate a report call, and other users can stake in to support the
reporter. Upon successful staking, the report is formally initiated, which will be voted
and determined by users of the entire network within 3 days.
When more than 50% of the votes support the reporter, the report succeeds, otherwise the
report fails. When the report succeeds, half of the staked tokens of the reported node will
be given to the reporter, and the other half will be distributed to the reporter’s
supporters according to the voting ratio. When the report fails, half of the tokens staked
by the reporter will be given to the reported node, and the other half to the node’s
supporters in proportion to the voting.
After a successful report, it will enter a new round of publicity period. During which
people are also allowed to report, but the staked tokens to initiate the report will be
multiplied by 2 times. The process repeats until no one ever files for a report in a certain
round of publicity period. Then the result of this round will be the final result.
The result has already been produced when the ruling is made, under normal
circumstances, users will vote for the correct result. If a collusion is plotted by the
whales, then they first need to hold the majority of governance token, which is costly,
and if they jointly kidnap the project and tamper with the results the governance
currency of such a project risks to become valueless, which will eventually cause them
to incur a loss. This is not worth the gain. On the other hand, should there be a successful
report against them, their staked governance token will be lost to the reporter. Therefore,
over the long run, nodes will be incentivized towards submitting correct results, which
ensures the fairness.

We are not worried about the similarity of the proposals. If users initiate the same prediction proposal, it means that this is a problem that everyone cares about. Under the same proposal, users can go to the community to call on everyone to participate in their own proposals, so as to get higher income. Competition will bring everyone’s attention, which means that for x predict market, the same proposal will bring more liquidity, it is up to the community to create diverse proposals.
4 Correct
Users can even buy Yes coins and No coins at the same time, and they can provide liquidity after the purchase. (To be clear, the Yes / No token are just lp token, which you can exchange for settlement token when the results are uploaded and the prediction ends. But users deposit settlement tokens as liquidity)

If we understand the meaning correctly, POT will be the only governance token in X Protocol ecosystem.
