Non-fungible tokens are used for representing assets like stocks, shares.

Yes, this is true. Shares might be in the form of a land or property owned by an individual or company. And as soon as ownership of that share is transferred anyone on the blockchain can see.

NFTs are not interchangeable as each NFT is unique and cannot be replicated.

I think it should be emphasised that most at times we tend to see companies having their nfts looking alike. What we call these are collections and Infact when we look closely they are unique.

Have you heard of the nft company; crypto bill society?

They have their nfts being bulls and at times their nfts look very much a like I must say😂(it happens in few cases though) most at times what differentiates them is that they put a cigar in ones mouth. But they are all unique.

When it comes to the sales of my personal nft , I will prefer setting an auction where people compete for it. You might end up getting a crazy bid from someone 😉

So my question here is, what if I set my nft on a limited auction for like one month and 3 days into I get a crazy bid from someone and don’t want to wait can I sell it immediately or I have to wait for the one month.?

Can a user also decide to withdraw his bid at anytime ?

NFTs are used for transferring ownership as players can sell their game collectibles and get real value for them.

Am someone who do not like playing games very much, but after realising that I can actually get something from playing a game I have tend to love playing now. Who knows I might end up getting an nft that will be life changing you know.
