It is still not clear to me what you want, but let see: you want to execute sqlplus for every Id you find, is that right?
I don't have how to test it now, but it should work!
In shell, I don't know a way to keep an Oracle connection opened (and I don't think there is a way, sqlplus does not support it!).
By the way, if you want this, why the first piece of code I wrote is not valid to you? It executes all queries in the FileName array sequentially, in the same connection!
If you really need to open the connection once, execute the queries and then close the connection, I suggest you to use another programming language.
My suggestion is: Python and its lib to connect to Oracle: cx_Oracle
Sorry but it is not clear to me at which point in the first code you are opening the connection.
Kindly repeat it marking the line for opening the connection.

I have a system that is throwing number of id's in files where each file has more than one line and each line has one id
right now i have a code to cat the files each 5 minute and pass each file content to the given array FileName -the array in my code is just sample for the dynamic output and it is not static like shown- and i do shell loop to do the following
select the next value from shell array using the loop number as index
open sql connection
run query using sqlplus bind variable and query about the given value from shell array
close the connection
all what i'm looking for is to keep the whole logic but loop after opening the sqlplus because this change will offload the oracle resources somehow as opening connection is considered a high cost action for resources
...
You could loop through the array, generate all SQL statements, assign that to a shell variable and then use that variable in the sqlplus connection.
Thus, you move the task of generating your statements to Unix and open only one connection to Oracle when you're ready with your batch of queries.
Now for the part that says that the array is dynamic and is actually being created by reading text files. In that case, you do not need an array.
You loop through the files, read the ids, generate the queries all the while appending them, assign the value to a Unix variable and then use it while interacting with Oracle.

In fact, depending on what your queries are and how you want to use their output, you might be able to use the IN operator, like so -
