> Daw (blow, of the wind): blow down?

I think it's "wad" backwards, as in "to blow one's wad".

> won = hesitate

The opposite of "now".

> le''aq = messenger

> Qun le''aq ≈ angel

Possibly qa''el backwards, from Michael, the archangel.

> tlhIneng = potassium

Possibly from xifan hol "fenix". Perhaps related to potassium burning in water?

> tI'var = pedal in a car

tI'var -> rav'It -> "floor it"

> 'aSteD = job, occupation

Possibly "a stead". Literally a place, but a stead can also by extension refer to one's place or role in society.

Alternatively, people may look for *a stead*y job.

A few puns have immediately stuck out at me:

Daw (blow, of the wind): blow down?

gha'naD (fodder): "Hello mudduh, hello fadduh/Here I am at Camp Granada . . ."

ghIp'IS (friction): where the GRIP IS

HapmaH (pea): Having to "pee" is a "wee matter".

la'rut'an (mica): "Natural" backwards. Maybe because mica is a natural substance, maybe because Micah Papp (better known as Manny the Hippie) went all "natural".

mo'bIj (latch): Jibboom backwards.

ngit (ride, as in a bicycle/motorcycle): Cycling helps you stay "fit"! A xifan pun, with f->ng.

ro'leSlib (barnacle): Bill, sailor -- Barnacle Bill the Sailor. My own prediction, *bIlbernaD*, wasn't far off.

roq (be fragile, delicate, flimsy): From "bROKen".

'a'baqa' (file, dossier, portfolio): Manila folders were traditionally made of abaca', a zingiberaceous plant also known as Manila hemp.

'achme (anvil): Anvils on Looney Toons (and Animaniacs) were always made by the corporation knwn as Acme. C->ch is a perfect match in xifan.

'aghnIDnem (fuse): "Mending a fuse", as the Beatles song goes.
