No. US one dollar bills were not made in 1950.
In 1950, one dollar was worth one dollar. Adjusted for inflation, one dollar in 1950 is just under $10 in 2014.
The only U.S. $20 bills with dates in that period were the 1934 and 1950 series. Most 1934 bills are worth about $22-24 in average circulated condition. Most 1950 bills are worth face value to $22. The exception is a 1950-E bill which retails for $45 to $60.
None of them. 1950-series $10 bills remain common among collectors. There's more information at the question "What is the value of a 1950 US 10 dollar bill?".
The U.S. did not print any $1 bills or mint any $1 coins with that date.
HAWAII-stamped bills were issued for use during WWII so any bill dated 1950 wouldn't be genuine.
The U.S. didn't print any $2 bills dated 1950. Please check again and post a new question.

It would be quite something to have, because there were no U.S. bills of any denomination printed with the 1941 date. The nearest 2 series of $20 bills are 1934 and 1950.
This is normal for 1950 $5 bills. In circulated condition, it has no added value. A gem crisp uncirculated note is worth about $15
Most 1950-series $5 bills are not especially valuable. The earliest in the series, bearing the 1950 date without a series letter, would be worth $18 to $20 in uncirculated condition.
If they are mint conditiion they are worth 45-70 if not they are worth their face value
$50 is all it is worth. No one will give you a penny more for it. I have several thousand $50 bills dating from 1950's through 2009. Each one is worth exactly, $50.
