Does it only block the frequency for credit cards and allow others like keycards?

It blocks all my bank cards and my work key card, so I would say it blocks any card that uses radio frequencies to transmit the information

how many cards does it fit?

No matter how many cards fit, as long as the cards are in a specific place. One card protects whole wallet, a normal size wallet. But if you have a very large wallet, you gonna need two；） hope it helps

Do these work on both the 125khz and 13.5mhz rfid signals?

According to the specs on the Amazon page, it works on the 13.5mhz rfid signal
