I think 5x7 is the smallest size where characters are still fully recognisable, which is why it's used on all common character LCDs. Beyond that, with things like this font, reading becomes more of a "recognise vaguely evocative custom glyphs" exercise.
The Atari ST had a 6x6 font (5x5 for most glyphs, 5x6 including descenders) that took surprisingly few liberties with the lower case chars. I'm going by memory, but this looks like an accurate rendition: https://fontstruct.com/fontstructions/show/876150/atari_st_6
Lower case "a", "e" and "i" are not ideal, but the rest look pretty good to my eyes! (The OS used this for icon titles, so there was only ever 1 row at a time. Probably recommended.)
DSLinux[1] used a 4x6 font for the terminal, I found that surprisingly usable.

English speaker detected! Half kidding, but in my language that would be difficult. ÅÄÖ
People got by using non-English languages in the 1980s when most computers only used ASCII due to their US/UK origins. Many languages already had such substitutions established, for example in German umlauts can be replaced with a following e, which were sometimes used on signs using block letters where there was no space for umlauts.
It's also missing Kanji/Hanzi characters ;(
