DJC at the viewpoint marker, beyond is a trig point [pillar] and one of the radio masts [NATS].

On a clear day like this, one can see six kingdoms - The Isle of Man, England, Wales, Scotland, Ireland and Manannan [or Neptune].

An ordnance survey benchmark, cut into the stone base of the wall at Molten.

WD is "War Department" [in the UK, the Ordnance Survey was, historically, part of the War Office, responsible for mapping territory].
This one may be damaged, as the broad arrow should be topped with an horizontal line, which is the levelled "spot height". Otherwise it's the point at which the angled lines meet.
Not quite sure of the meaning for the other marks.

On the corner building - an OS benchmark (spot height) - as you come out of Main St, Ravenglass and reach the foreshore.
Ben, with a new blue colour, has decided to take the opportunity for a quick lie down - we have almost completed a decent length of an easy circular walk. Ben, of course, has probably walked at least twice as far ...
