This forum can be thought of as your free OpenEMR IT support! Often it’s slow but the people who answer often are the very ones who coded the part of the application you ask about- can’t beat that!
In my case I’m not on the forum as often as many other contributors, but I have done user support for OpenEMR for about 6 years so do have help to offer. And growlingflea has been developing in the OpenEMR project for almost that long.
One resource I find that mysteriously very few people are aware of is the OpenEMR wiki documentation repository at:
Admittedly it is a bit disorganized, but then it has been added to with no formal plan for about 15 years. But that page does give access to documentation of most of the main aspects of OpenEMR. The only problem is knowing what the name is of what you’re looking for!
Another thing you’ll notice is that many of the docs were written for earlier versions of OpenEMR. However, most of the interface elements have been retained in the newer versions, merely moved around on the screen, so the instructions still apply.
Briefly about the ACLs, if your account has an Administrator ACL you’ll be able to see all the reports, so if one of your staff can’t access them, you can tell it’s an ACL problem and change their role to something that can.
About the patient reports you’re looking for, this page in the wiki (link below) has a good summary of all the reports. The doc was written for an earlier version of the EMR, but as I say, the controls that are used to set the report parameters are fairly consistent. Because of that you should be able to use any report in the system, as described in this doc.
As to the specific reports you mentioned, if you access from the Main Menu: Reports / Clients / List that will have the basic patient data of the pts you have seen in a date range (see output in image below).
Then look at the info available at Reports / Visits. That entire submenu is rich with useful info.
