It depends very much on its date and condition. Star notes are notes that are printed to re-use the serial number of a bill that was damaged during production, so for something as common as a $1 bill a star note is unlikely to be worth much more than the value of a standard note with the same date UNLESS the bill is either very old and/or in uncirculated condition.
In mint uncirculated condition, a 1990 $20 note is worth $30. In normal condition, it is worth exactly $20.
10 to 15 dollars depending on condition
A perfect uncirculated 1987 Mexican 50,000 Peso note is worth $60. A Very Good condition is worth $7.50.
No, but there is a million dollar bill note.
