Yes and, in fact, there are a plethora of adult thumb suckers who currently exist.
With the advent of the Internet the subject of adult thumb sucking has left the shadows and, as a result, it is now well known that adults do, indeed, suck their thumb. The best estimate, so far, is that affects about 2% of the adult population in the United States.

Yes you will your fingers or thumb pushes the teeth to the front and the top of your mouth goes up and u will most likely have messed up teeth at the end. if u do get braces do not suck on your fingers or thumb it will ruin your teeth permanently
Depending on the condition of the gums and jaw, usually not. Once the growth stage has finished, usually by age 14 or 15ish, an adult would have to suck their thumb, with sufficient pressure on the dental structures, more than 6-12 hours each day for years to have a remote chance of moving their teeth. If, however, the jaw bones and/or gums are diseased the chances increase proportionately and would, therefore, react to a thumb sucking force more easily but it would still take quite some time and effort.
No. But don't suck on your thumb, it's weird.
They CAN suck their thumb, however by that age, they should have grown out of it.
