Yes you can but only if only don't run out of resources or you don't exceed this criteria regarding building large clusters.

Usually you want to limit your jobs in some way in order to better handle memory and CPU or to adjust it in any other way according to your needs.

So the best practice in your case would be to:

• set as many jobs as you want (bear in mind the building large clusters criteria)
• observe the resource usage
• if needed use for example Resource Quotas in order to limit resources used by the jobs

I hope you find this helpful.
