I am^h^hwas working on a multi page answer but my computer died.
(I am borrowing a laptop to write this)
You can not drive relays, let alone 5V relay directly but you need to add a little circuit.
I found a picture on the web here: https://www.wired.com/geekdad/wp-conten ... driver.jpg
As I have no details of your relays the following are guesstimates.
For the resistor use about 1K.
For the transistor any** small NPN transistor should suffice.
For the diode any** small silicon diode should suffice.
**The Elector magazine would use the names TUN or DUS for those.
I found a website explaining that too here: http://www.sentex.ca/~mec1995/circ/tuptun/tuptun.htm
That list has rather (very...) old transistor but gives a good impression of what works.
Those transistors are still widely available.
