Not sure what size energy chain you have but I only just managed to squeeze 2 lines (1 0.75mm for the Z axis motor and 1 1.5mm for the spindle) in my smaller energy chain (this spans the gantry) and luckily I got a wider chain for the Y axis as it will have an extra lead going through it (Gantry motor).

My energy chain is this

and this one is the bigger stuff for the Y axis

I couldn't get my water lines in the chain but I didn't want the water running in the energy chain with electrical wiring anyways lol.
