No, not ideally. First, I think you should remove them from that Magix folder.
Then I followed this procedure:
On my computer I created a folder called "Magix VSTs" into which I copied the .dll files of ALL the VSTs and VSTis I have that I wished to make available to MM. I then, in MM, went to File>Settings>Program Settings (shortcut P) >Folders.
At the bottom of that screen is a button "Add VST plug-in path", you need to click it and enter the location of the folder which was previously created.
Now MM should see and be able to use all your selected VSTs (via the menu/screen in my earlier post) and your VSTis, if any, which will show up on the Instruments screen on the right hand side of the main work screen.
I put third party plugins in subfolders under the above folder. As far as I know, MMM and other Magix programs scan this folder by default for plugins. If new ones don't show up, rescan this folder or the affected subfolder.
When MMM goes to 64 bits, the plugin path will be:
The last image you posted suggests you have created a folder "Magix Plugs>VstPlugins" on your Desktop. That is definitely not advisable. Windows treats the Desktop as a Protected Folder, hence MM may well not be able to access it. You should place that folder on your C:\ Drive (if you have only one hard drive); I have mine on D:\, which is the drive where the majority of my programs are installed.
Once the folder is correctly located on the root of your drive (my exact location is D:\Program Files (x86)\MAGIX VSTs) make sure the setting in MM "Add VST plug in path" is pointing to exactly that folder.
One other thought: I don't think those Red VSTs can be 64 bit, but MM is a 32 bit program and, therefore, its plugins must also be 32 bit, unless you're prepared to buy, install and use something like jBridge which will enable a 32 bit program to use a 64 bit plugin, or a 64 bit program to use a 32 bit plug.
