I usually download icons as SVG or EPS since I'm usually integrating them as vectors into a larger project. However, if you want to display them in a more straightforward manner, PNG should work for you. Size is really dependent on how you plan on using the icon. If you're using it for a website (let's say on a button), you want them smaller. If you're using them for print, bigger is always better.
