They look ok to me except for:

A possible missing hidden line (horizontal dashed line) on third link lower drawing.

Some of the hidden lines look a bit "solid". I had to zoom into check.

Were you told which angle projection they had to be (eg first or third)?

The missing line is at the second picture of the third link right? Could you tell me which projection (the upper right/ left/ the lower) might be wrong?

Yes the projection in the top right quarter of this image appears to be missing a hidden line although there is a faint construction line for it?
