some of my smaller top windows can't be opened as there is no handle or lock.
Anyone knows how these can be made to open? How do I remove them in the first place?

The counter balance is not working correctly, but repairing this or replacing it is non-trivial. Instead, you can pickup a device like this that will create enough friction to hold the window in place. It should be installed between the window and the frame and is a simple DIY job.

From treehugger.com
"When air passes over your home, it works the same way as it does over an airplane wing: the Bernoulli effect causes the air on top and on the downwind side of the house to be at a lower pressure than on the upwind side. So if you have double hung windows, you can open the bottom section of the upwind side of the house (usually west) and the upper section of the downwind side (usually east), and the low pressure will suck the air through your house. Make the outlet openings (top section) larger than the inlet opening (bottom section), it increases the draft."

No hinge amigo. Time to get new windows if you want these to open.
