How much are these comics probably worth?

I got some really old comics for my birthday recently and my parents (who are the ones who gave them to me) want to know how much they are worth. Here they are:

The Jetsons Issue No. 2
“When Earth Turned Into a Comet” From Beyond the Unknown Issue No. 3
The Cisco Kid July-Aug.
Roy Rogers Comics Jan.
Walt Disney’s Comics and Stories 10011-101 January
Everything’s Archie Issue No. 14

These comics are very old and in highly good condition.
