Mezuzah placement Shaloh

Some pictures someone sent me, is there any svorah that the first doorway would need a mezuzah? (its missing the right doorpost... but is kind of close... and has no lintel but it the ceiling goes down which kind of give the impression that it does..)

The second picture seem to me to be straight out potur, but a general Shaloh, can a doorway to a room with no lintel but has a lower ceiling be in any way considered as a lintel? (think about walking down the stairs the ceiling is lower)

Thanks
