Here is a diagram explaining this problem. Essentially, the circles represent students. A and B represent Alice and Bob. We can see that there are 4 students between Alice and Bob. Thus, if there are 12 students shorter than Alice, \$12 - 5\$ (the students marked on the diagram), means that there should be \$7\$ students shorter than Bob. Similarly, \$14-5\$ means there should be \$9\$ students taller than Alice.

Adding everything up gives us an answer of \$7+6+9 = \boxed{22}\$
