Answer 1

Using substring function you can extract first five characters of the file name . I have reproduced issue from my side and below are steps I followed,

1. Created logic app as shown below,

2. Taken http trigger and then initialized a variable of type array.

3. Next listing Azure blobs in storage account.

4. In foreach loop, iterating over list of blobs and then appending display name of blob to array variable. Here using substring function to take first 5 characters of file name with expression,

substring(items('For_each')?['DisplayName'],0,5)

5. Creating blob with using content as array variable output.

6. File names in storage account displayed as shown below,

7. Logic app ran successfully and blob created in storage account as shown below,
