Can I use this in a regular 7 1/4 inch circular saw with 5/8 inch arbor?

Yes, you can use this with a 5/8 inch arbor. It is even stamped on the left side 5/8 with diamond knockout.

I need to cut an opening for a 30" wall oven. Will this blade be able to provide a very fine cut?

I used it to cut the bottom of two wood doors and it was fine enough for that. Usually, if you're cutting a wall, I would cut it by hand or with a reciprocating saw. Using a circular saw will cause a dust storm. Plus, the wall oven usually has a lip on it, and the cut doesn't have to be that fine because the edge of your cut will never be seen.

Can this blade cut a butcher block countertop 1.5 inches thick

Yes, 60TH + is best for butcher block cutting. Yes, the 7-1/4" blade will cut 1.5" butcher block

Will this blade cut 1/2inch hdpe without gumming up the blade?

I don't know for sure but I would think the friction of the blade would heat things up enough to gum up the teeth. I think a reciprocating saw ( saber saw) or a band saw is what you want and you can vary the blade speed to find out what works best.
