PPI = Pixels Per Inch. The density of pixels of a display. Every display has different size of pixels. Also various native resolutions for various displays.
There are some of the factors:
Pixel size
Display technology
Geographical layout of Pixels
Display dimensions
It is not that easy to compare everything but in general: High resolution at the same display size = more PPI. The same resolution on a bigger display = lower PPI.
Water drop notch is just a notch in shape of a water-drop. There is no defined shape. Just a marketing name.
Bezel free display is display without frames. When it's right in front of you, you cannot see anything else apart from the display. There are no phones with true bezel free displays.
