When the blockchain's transaction is reversed if there are two users at the same time doing exchanges. This usually happens naturally. But it can be done on purpose by a hackers with the aid of ample hash power. But this is hard to come by.

Nice copypasta, but no.

These are blocks that can be used in an attempt to reverse the transactions. These are normally caused by the attackers if they can generate enough hash power to be able to do such a thing.

No, not necessarily...

Orphan block is the part of main chain. It built for reverse transaction it can occur naturally when two miner produce block. I think its good for reverse tranaction.

It is not a big problem. You can get back your reward by using your privet key. it is also difficult but not imposibile. I think you will solve your problem as soon.

Not related to the topic AT all.

Why would you even make a post if you have no clue what it is about.. Couldn't you atleast google the definition of an orphan block?

I think this SE post covers the definition extremely well. https://bitcoin.stackexchange.com/questions/5859/what-are-orphaned-and-stale-blocks
