Dear Team,
We have only 5 users after 30 days trial can we still use it for free ??
we don't wont additional users only 5 users we use did we have to pay any amount or we can use it for free
That is not entirely accurate for all cases. While there are free plans for cloud, they have differing user limits. For Jira Service Management (JSM) the user limit is only 3 agents. You can also see this noted in https://www.atlassian.com/software/jira/service-management/pricing
If you were using Jira instead, then yes there is a 10 user limit on a free plan.
In order to switch to a free plan, if you are using JSM, you would need to reduce the user count to no more than 3, and then you can downgrade. When the trial expires, the product should expect to be deactivated for a period of time. Once that time has lapsed, if no other subscription is renewed, the site data could be deleted. You could in theory renew to a free plan, but only if you are under the user limit for that particular product.
Please also be aware, if you go to a free plan for Jira Cloud, these free plans have a 120 inactivity limit. If you don't use the product for 120 days, the product and the data in it will be deleted immediately.
