This thread is the perfect example of why monitor calibration is soo important. DO NOT waste your time re-editing the pictures till you calibrate your monitor. There is NO point. You will make them look good on one screen, and then when you share them, people will see a different picture than you.
Use some manual calibration and shoot in raw so you can redo the pics once you do get a calibrator. Personally I use the colormunki display and it works well for me. It also adjusts brightness based on the ambient light to help when the sun is down or it is cloudy, or I turn lights on/off, or the shades are closed.
Overall though, the pictures you posted look ok to me. Good colors and nothing blown out. Decent details in the blacks, good exposures. Right now, without a calibrated screen to work on, you will be beating your head against the wall. Maybe use a credit card or borrow one.
