You only mention the colours for one "gang" of your downstairs switch. (The red and the black)
The other "gang" of the downsatirs switch should be the same as the upstairs switch.

But yes, connect like for like, no problem. You would also be well advised to mark the cables with a pen then take a picture on your phone, then check to see if the picture is in focus.

Also most 2 gang switches are 2 switches, with one being upside down in relation to the other switch, but the markings are correct.

Sorry the other gang down stairs switch is as you said
Red wire Com
Blue 2 way
Yellow 1 way
Only changing the downstairs double switch as one of the rocker switchs is a bit stiff.
Same wiring colour up stairs but not changing that one.
Have changed one way switches before but not double ones.
Many thanks for advice.
