can I control thread group while running concurrently in Jmeter

Question

I have 30 different db queries. I want to run 5 db queries concurrently at any given time from 30 different queries. But it should not pick already executed query.

Like if any one query completed out of 30 db queries, it has to pick next query from 30 queries.

Can we achieve the above use-case in jmeter?. Please help on this.

2. For picking up unique queries the easiest is using CSV Data Set Config
