In total, 4, but two are used to start a new reaction so there is a net profit of 2.

There is a net gain of 2 ATP molecules in glycolysis, as well as in the Kreb's cycle. Electron Transport generates about 28 ATP molecules, so the grand total comes to 32 ATP in all of cellular respiration, although this number may vary, because the proton gradient energy is used to do work also, and the electron transport chain does not always work at maximum capacity 100% of the time. Some biology texts will tell you total ATP production is around 38 total. However, that is too high and just not the case.

Net gain is 2: Anaerobic glycolysis takes a six carbon sugar, glucose, splits it into two molecules of three carbon sugar, glyceradehyde, and then rearranges the atoms, to lactate. The rearrangement of atoms provides energy to make ATP. There is an overall conservation of atoms in this process. There are six carbon, six oxygen and twelve hydrogen atoms from begining to end. Watch this musical lecture 3 or 4 times it really helps:
