VBATT SENSE and PP BATT VCC are "signals." They may be I/O, sensors, even power from what you have shown. They go to something on the rest of the schematic. What is it that you do not understand?
The circled numbers may be anything. In context, they may be pin numbers on connectors.

is the one end of a bus (notice the darker line) that has signals BATT U3 300-A1 ...BATT U3 300-E1. The schematic happens to show and label each pin. The C1 signal goes here:

Note that C1 goes to multiple pins that are individually numbered C1...C3.
Those small numbers on the bus or signal lines that exit the page are probably page numbers. Except for the multiple pages, there is noting there that isn't in the free version of EAGLE. One may simple decide not to show that information.
