HighWire engine (2001-2010 active development, 2011+ maintenance)
Netkit (of the NetSurfer browser - 1994-1996? or 1998?; NeXTSTEP/OpenStep; nothing to do w/ WebKit)
WannaBe engine (1998-2002; text-based). WannaBe is a Gzilla fork (mindstory.com/wb2/docs/about.html) but only for 1998-2001; it changed rendering engine in 2001 and continued with it to 2002.
2 forks of Cobra: the gngr engine (2014-2022; also dead?) and CobraEvolution (of LoboEvolution; 2019+; alive)
engine of the Charlotte browser (for VM/CMS? VM/ESA? z/VM? documentation on it is very unclear) that started development before 1997 and lasted with maintenance until 2010? (edit; Seems to be a text browser: https://groups.io/g/h390-vm/topic/charlotte_web_browser/74969664)
engine of Aplix, the Japan-only browser for the Sega Saturn (1996-1997). (Nothing to do with PlanetWeb. )
Mnemonic. It was developed from 1997 to 2000 with its site formerly at mnemonic.org. I get the idea that it was an independent engine from what was written on certain captures of the page.
iCab: mention in the graph that while the engine is dead the browser with the same name still exists (using Webkit)

KHTML: discontinued in 2023 with the end of Plasma 5
