How to tell if same device was used for different images

[frankytanky87]

What in this data can definitively tell me if the same camera was used for these photos? Or what can I add to my commands to find out. Any help would be awesome. Thanks so much.

Those images contain very little metadata.  The ICC_Profile tags aren't going to help you here.

Maybe the best you can do here is to look at the JpegDigest (this tag must be requested specifically), but that won't narrow things down too much.

What in this data can definitively tell me if the same camera was used for these photos? Or what can I add to my commands to find out. Any help would be awesome. Thanks so much.

Directly from the camera, there should be Make and Model and probably a serial number tag (actual name can be dependent upon the camera).

Any such data can easily be changed so the images "match".

Also, files that pass through any social media site have most metadata stripped away.
