Hand-candy is simply another word for a penis. The defining feature here being the masturbation or hand job motion that involves a grabbing action with a hand, as one would a pile of candy. Candy is also something that one might later put in their mouth, and represents the penis as a treat.

A door wall is a sliding-glass door or patio door. The term is yet another example of banal Michigan vernacular, where in the residents latch on to company names, trademark names, marketing terms and product names from local companies. The terms become embedded in the local vocabulary and eventually become accepted as actual valid words and phrases. In this case the term comes from Wallside Windows in Taylor, MI (a large window manufacturer), where 'door wall' is their created word for sliding-glass door.
