It is not possible for editors to unlock all your articles. You need to provide the specific URL of which articles you are going to work upon and wish to edit. Note that you should not republish old articles which have not generated any traffic as these will eventually be archived during the tuning process of old articles. It is suggested to create a StatCounter account and check. This can be done through your Dashboard page. Under the heading of Site Settings, there is a link to Configure Stat Counter to track the traffic to your articles.
Further, please do not rely solely on the free Grammarly tool. The tool is not 100% perfect and often overlooks singular/plural errors and sometimes even suggests a word which actually is not fitting the sentence context. It would be a good idea to participate in forum discussions to improve English and writing skills. You have good topics, but need to work on the writing part. Avoid repetition of text as well. Be consistent in submitting articles and contribute to other sections also, not relying only on republished articles to get approval for Google AdSense. Focusing on quality should be your priority and once you have got a good number of quality contributions over the span of next three months at least, then you could apply again.
