Hi Dinesh,
Greetings!

You can do this even from a single Scheduled Job.
In your class.
1. Before execution of your code, fetch the current job from CRONTRIGGER.
2. Abort the job System.abortJob(cronId).
3. Now, Schedule the new job for after 5 min.
4. Execute your schedule class code.

If you find your Solution then mark this as the best answer. 

Thank you!

Go to Developer Console -> Execute Anonymous -> Paste the below code -> Select the entire code -> Click on “Execute Highlighted” (You can also just click “Execute”. However, if there are also other code on execute anonymous, it is always safer to run only the code you have highlighted).

Let’s say your batch class name is BatchApexIllustration.

System.schedule('Schedule Job Now',  '0 00 * * * ?', new BatchApexIllustration());
System.schedule('Schedule Job after 5 minutes - 1',  '0 5 * * * ?', new BatchApexIllustration());
System.schedule('Schedule Job after 5 minutes - 2',  '0 10 * * * ?', new BatchApexIllustration());
System.schedule('Schedule Job after 5 minutes - 3',  '0 15 * * * ?', new BatchApexIllustration());
System.schedule('Schedule Job after 5 minutes - 4',  '0 20 * * * ?', new BatchApexIllustration());
System.schedule('Schedule Job after 5 minutes - 5',  '0 25 * * * ?', new BatchApexIllustration());
System.schedule('Schedule Job after 5 minutes - 6',  '0 30 * * * ?', new BatchApexIllustration());
System.schedule('Schedule Job after 5 minutes - 7',  '0 35 * * * ?', new BatchApexIllustration());
System.schedule('Schedule Job after 5 minutes - 8',  '0 40 * * * ?', new BatchApexIllustration());
System.schedule('Schedule Job after 5 minutes - 9',  '0 45 * * * ?', new BatchApexIllustration());
System.schedule('Schedule Job after 5 minutes - 10', '0 50 * * * ?', new BatchApexIllustration());
System.schedule('Schedule Job after 5 minutes - 11', '0 55 * * * ?', new BatchApexIllustration());

In the above code we have used what is called the CRON expression - example '0 5 * * * ?'. To understand more on Apex Scheduler and the expression, refer this: https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_scheduler.htm
