Assuming the photo is one side of the "T" it looks like cars are only allowed to park against the kerb without yellow lines which they are so all cars are legally parked.It would be better to have a photo of all the "T" road to see the situation more clearly.
They're all parked incorrectly IMO, trying to get 3 spaces out of 2. Cars are allowed to park along the bit with no yellow lines and that leaves enough space for people to manoeuvre.
As for the Red car, it is parked more on the yellow lines than it is on the clear bit.
