Usefully, you can declare almost all of your variables to be register.
We just went through all this.  Since code written on one machine is
very often taken to others, and the word "register" isn't very hard to
type, you should declare almost everything a register.  Even data types
you don may not think fit in registers, like strucutures, enums,
doubles, and unions.

However, to answer the question -- 5.  The rest of the registers are
used for temporary values and other special purposes.
