Techically maybe, in so far as the food in the pictures come from animals' internal organs. They do. However, 'Offal' comes from an old English word meaning 'waste', and use of the word 'offal' suggests that the food in question has a low status; whereas the items in your pictures are clearly carefully prepared delicacies. They are!
What curious questions This is eaten quite often here in Argentina
The first picture includes some "bits" that might be offal, but also some that are definitely not. Definitely. That's the best picture I could get
Offal, to my mind, is any kind of animal stuff that is meant to be eaten but is not muscle (or fat).
The sausages in the first picture may be enclosed in intestine, but should, and I say should, contain real meat.
The black puding would not, of course.
Sorry, I can't access the second picture.
