Are these dishwasher safe?

I don’t know but there heavy rubber I would think they would be safe on the top shelf.

Will this break the seal like a jar key instead of trying to use a butter knife, and is it adjustable for jars with taller lids?

The main jar opener has 8 size openings, 4 openings each on the front and back for 1-3" lids, just choose the right size, grip and twist off the lids. For lids larger than 3 inches in diameter, you can use the Mouth-shaped hook on top helps to open large-size lid by breaking air tightness, please refer to the second and third pictures on the details page Hope this helps you!

Will this work for a stuck plastic cap with a 1.5 inch diameter?

It should. This has been so helpful in opening water bottle caps and jars. I've purchased as gifts for family & friends who have been needing more help opening jars.
