Cloth shoulder titles

[stef]

These came with a Belgium nationality title that was good, but I am unsure of these titles are also original WW2.

Brasil might be US fabrication?
Poland is RAF
Norway also RAF
Greece I don't know
The roundel is completely unknown to me, I tried googling it but could not found a match.

Not helpful I know, I have the Greece one, no idea what it is but it too came from the states.
