Are 28 / 47 - 622 / 635 tubes ok to replace my 28 / 44 - 622 ones? I recently got my first flat on my Cube hooper
It has 37 - 622 (28 x 1.40 - 700 x 35c) schwalbe tyres on it.

I ordered the new tube online before pulling the old one off, picking what I thought were the same tubes but the numbers are slightly different. 

Are the 28 / 47 - 622 / 635 tubes i got ok to replace my 28 / 44 - 622 ones?

Thanks
They would be perfectly fine. As their specification suggest (28 / 47 - 622 / 635 ) inner tubes can function in wide range of tyres.
