[...] Some questions: 1. Where is the basic size of the font family defined in points?
Hi John, the default font size is 12pt.
2. In the second example which of the many Dejavu fonts is assumed to be the starting point? Is it a ttf or a otf version?
As Joseph Canedo explained, the DejaVu font seem to be a TrueType font. This may be (and I think it is) a font in OpenType format with TrueType outlines (instead of PostScript outlines).
3. Can any font family on the system be used or is there a specific context list?
Any system font (TTF, OTF and PS at least) can be used with ConTeXt. All that ConTeXt (or LuaTeX) requires is the way to find it. The safest way is the file name. Let us know whether you have further questions. I hope it helps, Pablo -- http://www.ousia.tk
