Quick google says the first one has something to do with the CCA of your battery being too low. Probably worth changing if original.

Second one is for your thermostat - it's failed. Fortunately, they fail open so you aren't in any real danger but your engine will take longer to get up to proper operating temp and thus be less efficient. Most people will probably tell you to change the waterpump too but I can say from experience that it's not necessary.

Third is for VANOS solenoid, specifically the exhaust side. I would try cleaning first, you can find instructions in the DIY sections.

How many miles have you gotten out of your water pump post thermostat install?

I don't have a good number for you off the top of my head, but I'd guess at least 20k so far (and still no problems). It's been a couple years for sure.
