Answer:
Informal
Explanation:
The people in image 2 are not dressed up. They are wearing white T-shirts with cargo shorts. They also appear nervous or are being asked a question.
The people in image 4 seem to friends of some sort. They are exchanging hugs and are probably saying goodbye. This situation is also informal, as it is just a nice thing to do when saying bye to someone you know.
