How do I use the cheeses I got in a Christmas gift package?

Joy_Brigade asked: I got a Christmas gift from boss that has cheeses in it I’m not used to using. Pretty much I usually only use shredded cheese to put on a salad or taco, and sliced cheese for sandwiches.

In the package are round packages, and rectangular blocks of;

‘smokey bar’
‘gouda cheese’
‘butterkase’
‘chedam’

How do I use these? [...]
