If you are mainly shooting street and portraits, then the following two lenses are a must have:
XF23 f/1.4
XF56 f/1.2
I do own the APD version of the XF56, because I like the extra soft bokeh, but the standard lens is already awesome.
The XF23 is the perfect street lens as it represents 35 mm focal length. I also do a lot of portraits with this lens. If I would only had to stick with a single lens, the XF23 would be my baby. It is super sharp and fast and I love the manual focus capabilities. For your case, I would highly recommend the following four lens setup:
XF10-24
XF23
XF56
XF55-200
You might even not need the 55-200 and go with the XF90 or XF50-140 instead. But as you already own the 55-200, I would stick with it. But for street and portraits, you need the XF23 and XF56. Without those two babies, you are definitely missing something...
