I've checked my car with TechStream and found codes as below

how many miles on her?

does she burn any oil?

have you cleaned the egr circuit?

did you click on the snowflakes for sub codes?

 

For starters your screen shots are really hard to read... Hopefully if you have to post more you can get all the info into one image so it's not so confusing.

Secondly, as the years go by a car will pick up an occasisonal DTC that's not of any more significance than a one time glitch. So first step is to record all these codes and clear them all and drive around for a while that see what comes back.

Once you know what continues to be a problem you can do a Google search on that error code with keyword "priuschat" and read all the info on how to complete the diagnoses and repair.

 

C1202 is an issue with the level sensor for the brake fluid. If the fluid isn't low, the level sensor or wiring has an issue.

Some maintenance procedures involve temporarily unplugging that connector (it's a two-pole connector just under the edge of the cowl, just outboard of the brake fluid reservoir). Could be worth a quick check to see if maybe the last person to do that forgot to reconnect it.

C1252 indicates the brake pressure pump has had an excessively long run time. (One normal run of the pump usually takes a few seconds. The threshold to trigger C1252 is nearly three minutes.) What have you been noticing about the sounds of the pump?

The U0073 indicates the skid ECU isn't reliably communicating with some of its remote sensors, like the yaw rate and acceleration sensor or the steering angle sensor. The troubleshooting for those communication problems can require some attention to detail (and the manual and wiring diagram). It's the kind of code you might not worry much about if you clear it and it stays away.

The B2784 refers to the antenna coil built into the power switch. It's used when your smartkey wireless functionality isn't working and you have to start the car by holding the fob against the power button. If that antenna doesn't work, you could have an unhappy moment if you're ever in that situation.

I'm not sure what's a good way to test that (follow the repair manual, I guess). There is a chicken dance to disable smartkey, and then you would need to hold the fob against the button to start. But I don't remember if the dance involves pushing the button.

If it does, and the antenna's not working, you could probably do the dance to turn smartkey off easily enough, and then confirm you had a problem, and then, umm, not be able to do the dance to turn smartkey back on. That would be an unhappy moment.

Again, you might see if this code was a fluke and stays away after clearing.
