The five digit numbers are the raw samples of the sensor (captured at 24Hz). If you graph them you will should see some peaks and troughs corresponding to heart rate. You will also likely to see noise and a massive drift in the zero point. I believe from the literature that this is normal for PPG sensors and you will need to filter that out before doing any peak detection.
It's extremely odd that your files have only one time and date stamp though (there are four date stamps in the data you printed as part of the original question). What are the file sizes?
