We might not talk the same thing.

"2年自学10几门外语" is likely, as long as he has time and energy, and they are useful.

"一生精通22门外语", I would say just becareful to use 精通. It could be true no one gets chance to check this.

"一个晚上能看日语." is likely, but not to say master a language in one night. Believe it, guys knows English pick up German very quickly- they share several thousands words. Get a couple of days to get familiar with German grammar, one is able to read scientific articles is rather short time.
