I have three main families of fonts, the Da Lekh fonts and the Lamphun font, both of which primarily serve the Lanna script, and the LKLUG_T font, intended for Pali written in the Sinhala script.
The Da Lekh family is described and indexed here. There is also a glyph chart.
The Lamphun font is described and indexed here. There is also a glyph chart.
The LKLUG_T font is described and indexed here.
