If you look at the material provided form the Matlab site you'll see these explanations:

quad:

Numerically evaluate integral, adaptive Simpson quadrature

quadl:

Numerically evaluate integral, adaptive Lobatto quadrature

dblquad:

Numerically evaluate double integral over rectangle

I didn't look for quad8 as it wasn't readily available, but I'm sure that you'll be able to find it from here. Also each of the link provide a greater detail as to how they work exactly.
