The male XLR outs on the monitoring section provides challenges! 
What is the best and easiest way of turning two XLR’s into a mini TRS 3.5 female jack?
Sorry if this is a silly question but i don’t find the cables i want which would be a y-cable with 2 x female XLR and one stereo 3.5 mm female.

What are you trying to do? Maybe the Alt-Out would be an easier connection to use?
I want to give three persons individual stereo monitoring with headphones.
Ah, OK - so 5/6,7/8,9/10 out on the XLR.
I presume these are line level, so a headphone amp would be recommended anyway. Some of the cheapest headphone amps are on very small mixers - which will accept the XLR output…
Better ones will take TRS balanced or XLR directly…
I agree with Bob and can’t really think of a better way as your going to need a headphone amplifier or similar.
