Thanks for your questions! For clarity, AEM stands for "Adobe Experience Manager" which is one solution within Adobe Experience Cloud that enables users to make experiences on pages, etc.
Adobe Target is another solution within Adobe Experience Cloud that enables users to target experiences to certain audiences to generate lift etc.
Shruthi's response explains that you CAN use Adobe Target on html pages, as long as the html pages have the target libraries on them. You can read more about this here: Implementation
Hope this helps!
