2,000 psi compression
Depends on ground level and the length of your post, but the block is 8 inches in height.
Need corner posts in concrete, no but you can. If your worried about high winds anchor the deck which like posts in concrete defeats the ability for these to move with the dirt under them. https://www.homedepot.com/p/ShelterLogic-30-in-Earth-Anchor-Set-4-Piece-w-Heavy-Duty-Corrosion-Resistant-Steel-Construction-and-Spinnable-Corkscrew-Design-10075/202719050?MERCH=REC-_-searchViewed-_-NA-_-202719050-_-N
Any 2x? will work in the cross hatches, center fits a 4x4 on end.
Depends on whats inside. They are rated for 2,000 psi. each. I have these under my 30x30x10 shop.
No, they're meant for 4x4 to rest on it for e.g. a deck.
Would not recommend for use. Not designed for stacking. If you need heighth, a 4x4 post will sit securely in the middle of the cross section.
Absolutely. I've used them for my firewood shed.
Drill a hole in the center of the block, and another in to the 4x4 bottom. Use something like a length of re-bar of metal dowel to join the two together. Probably would need to get the hole in the concrete block about 6" deep, and at least that in the wood--8 to 10 inches would be better.
Pea gravel seems to work best for leveling if you need to dig and level
