aittle lock tite on the thread may work. other than that the thread in head is worn ,.this can be corrected by removing head ,retapping the thread and replacing head. maybe even easier just to replace the head with a new one
it could be an exhaust leak, a bad plug wire, loose spark plug or a lifter. check the oil.
You will find a loose electrical connection where the spark is occuring.
the engine is constantly vibrating and it dislodges the spark plugs
Spark plugs do not loose power, rather, they become worn and erroded. On occasion they may also become fouled, indicating a mechanical or fuel problem.
If you have a loose spark plug, your car will not stall unless maybe your engine has 3 cylinders. If you have a 6 or 8 cylinder engine you would just loose some power and your engine would run a little rough.
Change your spark plugs!!

Loose spark plugs would result in a loss of compression. This would make starting difficult and if the engine ran at all it would do so badly.
To remove the stuck spark plugs, you can break them loose and then start to get them tighter as you rotate them out. The ratchet wrench can also be used to remove the stuck spark plugs.
possibily its the wrong plugs could be hitting the pistons
If your Honda CRV cranks but won't turn over because the spark plugs are not getting spark, ensure the wires are connected. A loose spark plug wire can cause this issue.
