Lego: broken/incomplete sets (Harringay Ladder N8)

This Lego was unfortunately sitting in the sun in a heatwave and the pieces got very slightly melted, so they don't all snap together they way they used to. Could be assembled carefully and left on a shelf, or glued. Also the sets are incomplete - most of the pieces are there but some are missing.

I do have the instructions for every set. The photos show which sets they are.
