What are their dimensions folded? What about expanded? How much clearance do they need? What is the angle the extend the surface to?

The height after folding is 4in, the height after expansion is 9.5in, the angle formed from folding to expansion is 45°,

How much weight can one hold?

One of them will hold between 100 lbs when it is opened.

I haven't installed these yet. Just opened one from the package and it seems that without pressure it wont close. Defective or am I missing something?

Not defective. They are spring loaded. The pressure is the energy needed to lift whatever you attach it to.

Just purchased these, how can you keep the hinge down? Mine seems to start at the position I would like it to end at.

The two supporting pillars can move left and right, and by pushing them in a direction that can be closed (folded), a slow closing action can be achieved. You can check your installation. Just you need to align one side of the closed hinge with the edge of the installation side panel, screw in the screws, fix the hinges on the left and right sides, locate the hole position on the panel, and tighten it with the screws. Please note that the positions of the left and right hinges must be consistent, and the positioning of the panel holes must be measured with the hinges closed.
