Nothing wrong with errr... "economically disadvantaged" bikes. Any bike is better than no bike at all!

As GA mentioned, these are known as "friction shifters" as opposed to "indexed shifters" that you mentioned you were more familiar with (the ones with the numbers on them).
What you have are specifically known as Stem Shifters because, oddly enough, the
shifters are mounted to the
stem of the bicycle. These kind of shifters are great for a budget ride because although they aren't as "nice" as indexed shifters, they are very simple in their operation so they don't break as often and if they do, they can be easily repaired by someone with minimal tools or mechanical knowledge.
Your bike probably doesn't look exactly like this but the picture gives an idea of some of the bike part names. (this bike has indexed shifters built into the brake levers so ignore the fact that it doesn't have stem shifters like your bike does)

To use the shifters, you need to be pedaling at the same time as you move the levers. If the bike is stationary and you try to shift it the chain never actually jumps from cog to cog and the lever will spring back just as you describe.
Begin by finding a safe area to ride in that is free of traffic or other obstacles. Hop on the bike and pedal slowy in a straight line. As you pedal, move the right shift arm slowly but smoothly forward/down and you should feel the shifter on the back wheel hop from gear to gear. When you find a ratio you like, stop pushing the shifter and let go of it. If the chain is noisy or skipping back and forward between two gears you may need to push or pull the shift lever a little bit more to get the chain centered over thee gear you wish to ride in. It takes a bit of finesse to stop the shifter at exactly the right spot each time but practice makes perfect. You can do the same thing with the other shift lever to adjust the front gears (known as chainrings).
In Summary-
• Only shift when you are pedaling.
• Use finesse with the levers. (slow and smooth)
• Practice in a safe place since you'll likely tend to want to look at the shifters rather than the road ahead until you get comfortable with them.

Correct. The angle of the lever relates to what gear you are in. If you want to better understand the mechanics involved, hang the nose of the saddle of your bike over a tree limb so the bike is suspended off the ground. Crank the pedals with one hand while pushing/pulling the shifter lever with the other. This will allow you to watch what the shifter is actually doing and give you a better understanding of how friction shifter work.
I hope I've explained this without being too wordy. If anything is still unclear or you need additional assistance don't hesitate to ask. We all started somewhere.
Happy Pedaling.
