Yxmördaren Julia Blomqvist på fäktning i Schweiz
Schweiz för lyxfjäder på qvist bakom ugn
FAQ om Schweiz: Klöv du trång pjäxby? - this is an incomprehensible sentence, though it must be said, it does sound Swedish when spoken.
Yxskaftbud, ge vår WC-zonmö IQ-hjälp - this is also incomprehensible, plus the first word seems to be misspelled, it should be “Yxskaftsbud”, the missing s makes it hard to pronounce
Gud hjälpe Zorns mö qwickt få byx av - a sentence with old spellings and words, and rather naughty meaning, this sentence also misses the letter V, in the past when w and v could be used interchangeably it would be a proper pangram.
Byxfjärmat föl gick på duvshowen - misses Q and Z, but has the combinations fj and fö, which is very useful to test fonts for Swedish compabillity.
Tjock ges BMW på quiz, hänförd av lyx - one of the best pangrams here, it contains every letter and, even better, is perfectly logical.

Just fyi, number 5 isn’t missing the letter v, “av”.
