If referring to American gangsters, you would say "(der) Gangster." If referring to German gangsters, you might say something general like "(der) Verbrecher" or something specific to the organized crime group, e.g. "(der) Mafioso."
"Deutscher Gauner" would be the term you are looking for.
You say "Gangster" actually (same as in English). "Verbrecher" is also possible, but this is more general and means "criminal."
There is no direct translation for "mobster", The word that is most used, is the English word "Gangster". or a villain, swindler, thief or racketeer is a "Gauner"
