Both the red and grey look fine from the photos given but to be absolutely certain additional photos are necessary for both.
For the red one, if it is a mini, you have to see the length of the chains to be certain (Look at photo no. 5 of the grey one you provided, the length of the chains are correct for a mini). You need a photo of her holding the red bag or a better display of the chains.
Note how an authentic mini looks and the length of the chains.

For the grey mini, you need an additional photo of the logo on the interior pocket and if she has any authenticity tags.
