There's at least 4 fonts in the pic
- GNU Unifont, which is my default font
- Mona Gothic Wide (from the xfonts-mona package in Debian) is the font for the ASCII art of Nagisa Momoe
- Sony Fixed is the fixed serif font in the upper middle window
- Adobe Helvetica is the variable pitch in the upper right window
The font in the Solitaire (xsol) window is probably the default Misc Fixed font that comes with X11.
