Nice #GeoQuiz :)
There are 4 pins on the interactive map isspix.com/ISS073 for your post.
"Vaguely speaking" - so others can do your quiz - they are: western #Canada, near enough to #Australia, somewhere in southern #Africa, & around central #Africa.

I saw #CopernicusEU tweet "Rising to 2 022 metres, Mont Idoukal-n-Taghès is the highest peak in Niger & a prominent feature of the Aïr Massif...", so I looked for recent #astronaut pics of the region. These two are by #DonPettit. There are three #Niger pins on isspix.com/ISS072 for these. (See alt)

Do you see the lighter shades towards left / slightly darker towards right on this? Kind of a diagonal line demarcating them, too? That line is pretty much the border of #Angola (right) and #Namibia. Click for complete pic and more info in alt-text. Original high-res available on isspix.com/ISS073

Just a few hours ago, International Space Station’s orbit aligned such that NASA astronaut #JonnyKim took pictures of #HurricaneHumberto; this is one that he tweeted.
There are 2 blue-JK pins on the map isspix.com/ISS073 for this: 1 near #Grenada (his location at photo time), has hint for the other

Photographed by an external camera on the International Space Station, this is Northrop Grumman's Cygnus XL cargo craft. Looking carefully at the original, a road near #Chior & #Hongor, #Mongolia is evident. A map-pin is "at that spot" & has high-res link on isspix.com/ISS073. More in alt-txt
