Hypoid gear oil Genuine spec 235.0 technical question

I just bought some Genuine Mecredes Benz Hypoid Gear oil 85w-90 part number 000989280312 Spec 235.0. One question that I need answering would this be considered GL-5? Also if possible I would like to know if it contains a friction modifier for limited slips and is it conventional or synthetic?

This may be of some help. It is not for clutch based differentials that have limited slip. Here is a list of all MB approved 235.o gear oil.
MB 235.0 - Hypoid gear oils (SAE 90, 85 W-90, Specification 235.0) - Mercedes-Benz Specifications for Operating Fluids

If you study page 15 of the Aral catalog, they make Aral Getriebeöl HYP SAE 85W-90 (which has MB-Approval 235.0) and Aral Getriebeöl HYP LS SAE 85W-90 (which has a limited slip additive, but no MB-Approval).

The answers to your questions are: GL-5 yes, LS friction modifier no, conventional/synthetic don't know. (probably conventional)
