Depends on the series. If it is a modern series (1970s-present) as a set they might be worth $21-22 (though good luck getting someone to pay more than face value for them). Early sets or silver certificates are worth a premium.
20 times $50 equals $1,000. Consecutive serial numbers will only add to the value if they're old bills.
$20, American.
$150.00 They have no other value
Face value only.
As a form of identification and tracking, as well as accountability with the US government.
Enormous numbers of $2 bills were printed in 1976 for the Bicentennial celebration, so it's not unusual to find them with consecutive serial numbers. If they're from change, they have no extra value. Uncirculated ones might bring $3 to $4.
In circulated condition they have no extra value. If they're uncirculated you might get $3-$4 for them but that's only because they're uncirculated rather than consecutive.

$100....
not rare at all they are counterfeit broski
Modern-date bills with consecutive serial numbers in a small group (in this case, 5 bills) are relatively easy to get from a bank. In general, they have little or no added value. If they're all uncirculated, they'd probably be worth more for that fact than for being in sequential order. Even so, 2003 bills are new enough that an uncirculated one might retail for $3 or $4 at most.
The blue seals indicate your bills are silver certificates. In circulated condition the consecutive serial numbers add only a small amount to their normal $8 to $10 retail value.
If they're modern bills (1976 or later) the fact that they're consecutive doesn't add much to the value. Uncirculated ones would sell for about $3, and anything with wear would sell for face value or a few cents more.
About $50.
It depends a lot on their dates. If they're modern green-seal Federal Reserve Notes or 1953 / 1963 red-seal US Notes, the fact that they're uncirculated is more important than the consecutive serial numbers. You might be able to get $2.50 to $3.00 each for the FRN's or maybe $3-$4 for the US Notes. If they're older, you'd need to consult with a currency dealer who can examine them in person.
The value of a five dollar bill is five dollars. It's not clear what you mean by "consecutive serial numbers." If you mean that the bill's serial number looks like "12345678" or something, then a collector might be willing to pay a small premium for it as a curiosity. If you mean that you have two or more five dollar bills where the serial numbers are consecutive, they're worth five dollars each, period.
Without knowing the bills' date and series letter, it's impossible to estimate a value. Please post a new, separate question with that information. The series letter, if any, is a small letter next to the date. The fact that the serial numbers are consecutive doesn't add much to their value nor does the star indicating these are replacement notes. However depending on the date and series, those conditions combined with the fact that the bills are uncirculated could add to their collectability.
