While taking EDS (integrated into an SEM machine), lighter elements like Carbon and Oxygen show compositions which are nearly impossible in my sample according to phase diagrams. Are these results believable? Or are the lighter elements somehow don't show proper results? Is there any way to know for sure? I mean, can WD-XRF give better results?
Thank you for your opinion in advance!
The EDS spectra just provide the tentative idea about the composition or element present in your sample material, some time lighter elements does not give peaks.In order to confirm more qualitatively then you have to move towards XRF techniques.

Properly performed EDS is "believable" (unbelievable results are due to poor understanding of EDS). But if you do not need good spacial resolution (it's what EDS for), then why you are using it? For bulk specimens XRF (and many other techniques) is better.
In line with the above discussions I can say that better information about composition can be obtained by XRF.
