All depends on the subscription you chose. The most popular is probably the 10 standard assets per month. You can check your current remaining allocation by going to: https://stock.adobe.com/. If you are logged in, you will be shown your remaining images.
Please note: Unused assets carry over to the next month. They expire, however, after a year, so that with 10 assets per month you can accumulate a maximum of 120 assets.

I reviewed your account using the Adobe ID you are using here on the forums. I can see that your team has several subscriptions but none of them include Adobe Stock. However I see that you or your team members have taken advantage of our free assets.
