Yes, it will be a mess until you get things configured because she has been the admin, so all these things did not need new settings. You will need to configure separately what applications she can use as well as website she can access, etc. I'm afraid you will have to visit those websites to find out what they are because you won't know based on an IP address. Sites with the "https" are secure sites. Unsecure sites do not have the "s".
I'm afraid I don't know what uHD-UninstallAgent or uHD-LogRotator are, but they don't appear to be OS X components. I guess you will have to do some research using Google. I don't know what she has installed on the computer, and whatever she did install you will need to find out what it's for. She may have installed anti-malware software which may not be needed and could be uninstalled.
The two items above are apparently from something called Blue Stacks. It's an Android emulator. Maybe that is a clue for you. I don't know why she might want it on the computer. Maybe she just wants to be able to use Android apps but doesn't have an Android phone. Because these are not known apps for the managed account you will need to provide permission to use it now that she no longer is an admin user. The messages keep returning because you have not selected one of the Allow options. Allowing always will make the requests stop, but gives her unlimited access to that item. Once means she can use it this one time, but you will have to allow it every time she wants to use it. OK just makes the alert go away but does nothing.
