When SI units combine, they create derived SI units that are used to express physical quantities. These derived units are formed by multiplying or dividing the base SI units. Examples include the Newton (kg*m/s^2) for force and the Pascal (N/m^2) for pressure.
The SI has 7 base units. These units can be combined in an almost unlimited way to form other (derived) units. The Wikipedia article on "SI derived units" lists some examples.
Si and metric are the same thing. SI was a redefinition of metric in 1960.
