are they ok for a smith&wesson 686-6model

No idea but if it's a CO2 pistol then should be OK Ring a gunshop and ask !!

Is this for 20 or 5? Main heading says 20. Description says 5.

It is for 20, the capsules actually come in boxes of 10. The "5" seems to be misleading. Cannot say how good they are though as the pistol I bought them for had to go back to the manufacturer before I got to use them

Will they work with a 1.77 air gun

Only if the air gun is designed to work with 12g CO2 capsules

question but how do u store co2 bulbs safely

If for an air pistol/rifle keep separately and away from direct heat. Remove from gun after use even if not empty.
