Are these Bacterium?

Took these today under my microscope at 125x. They're a culture of yogurt + milk, for 3 days at about 27*C. Are the circled items bacterium? (All the possible bacteriums, are actually blueish, the camera didn't get the color, and #2 and3 have the shape when overfocused, like http://en.wikipedia.org/wiki/Image:Streptococcus.jpg)

Zooming out of the pics may help clarity since they're very large.

I'd say yes. However it would help if you could indicate the size of the scale that you see in the pic (just stating a 125x magnification does not help per se as the image itself can be enlarged).
