It would be best to get the original images than importing images from word, unless this document is to be purposed for internet use only.
To release it from the anchor you can just Cut and Paste the object. But you can only select one anchored object at a time.
Personally, I would not import the inline graphics. And if the only graphics were inside Word, I would print that Word document to a PDF and use Acrobats Professional tool to Export all Images under Advanced>Export All Images
The unfortuante thing is that Anchored Objects are treated like text, and InDesign won't generate an object style for imported graphics, or imported inline graphics.
I'm not sure why you would want to release the Inline graphics, the persumption on my part is that you want to move the images around easily or something.
The best way I can think of is to edit the Anchor Object settings for one Image and get the settings are right as you can. In the Object Styles you can assign a ShortCut to that style, as you edit the text and are moving through the document you can apply the anchored object style via the keyboard short cut.
This will keep the images in the order they appear in the Word file. But I strongly urge you to try get a hold of the original files.
If you can't you might try the PDF effort by making the word file a PDF and in Acrobat Profession use the export all images from the PDF and then you can place them at your leisure, you can then forego the importing of Inline images to the Indesign document.
