Assuming you're using Bitcoin Core, all of them are impossible. If you wish to do it,
1. Follow @DaveF suggestion to use your own DB, which is indexable.
2. Follow @DaveF suggestion to use third party API.
3. Host your own blockchain explorer using open-source bitcoin block explorer. I took a peek at mempool.space and esplora API documentation, but it looks like it doesn't have feature you're looking for.
Topic: Querying data from Full node ? (Read 123 times)
Short version....you can't.
You are going to have to pull that data into a DB and query the data from there.
Otherwise every time you want to find out something you are going to have to parse the entire blockchain.
https://blockchair.com/ has a very good API that is fairly cheap to use if you do not have that many queries that you will do every day.

I am having a full node. What do I do to fetch data from it as per the user requirement ?
Let's consider the below examples with x = any random number
1. I want to receive all address "with x+ BTC"
2. I want to receive all transactions "in last 24" hours which transacted x amount
3. fetch blocks between date ranges
4. fetch transactions where fees was x
If it were a normal SQL database we could have used SQL queries such as
Select tx from full node where amount=x
but I am not sure how to receive block data from the full node.
I want to develop a program where I can code to retrieve the above data.
