if you are having url as attribute to the flowfile then you can use update attribute processor with replaceFirst function to replace 5 characters with empty string.

Example:-

I'm having url attribute to the flowfile with value as

https://community.hortonworks.com/questions/182384/how-to-remove-just-only-5-characters-from-url.htm...

Now i'm using update attribute processor and added new property in update attribute processor

url

${url:replaceFirst('\w{5}', '')}

(or)

${url:replaceAll('^.{0,5}', '')}

Output Flowfile Attribute value:-

Now we have removed first 5 characters in url attribute value by using update attribute processor.
