Eyes on roof-top

Uma used to laugh ... on one of my habits. Once, I told her of my habit. And later, she used to show me, if my interests are visible. Though Uma is not with me now, I remember her whenever I see something of that sort.

I am talking about my habit of looking around, even on rooftops ! You know, I look at cloth lines. Something of interest will catch my eyes. Today, when I was in my office, my eyes made a quick scan. And on the next roof-top ... ther's something.
that's what you see below.
Now, the question is ... Identify the items. Atleast the left three. Anyone?
