No, it is intended for wood and soaks in too much to look good on concrete. HD sells a good variety of concrete stain.
Yes.
There is no difference. They are one in the same.
yes
No. You can use lacquer on oil too. Varnish will work well with oil stain as do any of the wax finishes
Generally, yes, although the water-based stain may run a small amount after application if the wood still has a lot of oil present in it. After 15 years, it should be okay.
Yes, you can

It depends on the type of stain you are using, usually the label contains the correct information, oil based stain generally takes 24 hours, water based takes less time, alcohol based takes even less time. If there is no label, it could be old stain and it might not mix well with your finish. your best bet would be to discard and buy new stain to match with your finish. (water based stain with water based finish, and, oil based stain with oil based finish)
Yes! Providing that the stain in question is "oil based"! If the stain is LATEX then no. Oil based products will mix, but oil and water won't! Water being the carrying agent of latex!

Yes you can if it is a solid stain. However, if you're using toners or semi-transparent stains, you'll want to remove all the water based product prior to applying the oil based stain, otherwise, it will appear blotchy if the water based stain is worn unevenly.

Start by scraping off everything you can with a spatula or similar tool. The stain and residue on the concrete may be permanent, but you could try concrete cleaners designed to get oil stains out.
Either concrete stain or block and stucco paint. I painted an eagle statue ,about three year's ago with oil colors and after it dried i put a coat of polycrylic, (by Min Wax) over it and and it still looks great.
