Attached are the pictures of newly constructed basement wall. I wonder if these defects are going to be a problem in the future? Outside of the walls have water proofing, but I wonder if these defects will lead to problems with water leakage or structural issues.
Picture 1 – Honeycombing type effect – both side of door opening.
Picture 2 – line across the middle of the wall.
picture 3 – line across under the window and in the corner.
picture 4 – line in across the middle area
Are those type defects normal in the concrete walls?

Well, these 'issues' so to speak are rather commonly seen on smaller construction sites (at my area of living) and are result of problems/mistakes while concrete laying. Probably all of them (as far as I can see from these pictures) are made by poor concrete thickening (without or with poor use of concrete vibrators or other devices). These, ideally, shouldn't be made by proffessionals, but they are still being seens here or there.
With proper water insulation these shouldn't cause trouble, unless they are deep cracks (concrete layered with too long interval and not thickened). Even if with cracks, structures are often over-designed for stress, so I doubt that it may cause any harm.
If I were You, I would rather look into proper and precise water insulation making - most often a real problem.
