Would this product be good to unlock an old engine that is locked?

If the pistons are not TOO seized, yes. If it's a block of rust, no. Excellent penetrating lubricant if you can hit it from the bottom (remove oil pan and spray down all cylinders) and the top (spark plug holes). That will give you the best shot.

is this an aerosol product?

Yes it is !! Thanks for inquiring. Fred!!

Will this loosen the swivel on my patio chairs that no longer swivel?

It depends on how bad the swivel is rusted. I used Blaster on rusted bicycles that were left out all winter in Massachusetts near the coast. The salt air was not kind. Blaster was able to remove the rust on the back and front gears and enable the wheels to rotate. However the chain on one of the bikes has spots where it is not free and has kinks. The front head post where the handlebars connect to the front forks does not swivel freely. This may be fixed by taking the head apart and getting to the bearings. Blaster works better than any other rust remover I have ever used but it is not invincible.

Does this come with an application straw, straw not pictured?

My came with a straw built in. I also know some do do not have built in straws.
