The 03:50 ADB departure is a Lufthansa flight and operated by Lufthansa if you're booked on it. The later morning and the afternoon flight is operated by XQ.
AFAIK, the baggage allowance would be the same as your LH ticket but no fast-track security nor lounge access. However, Priority Pass would allow you to the lounge in ADB.
If you have a separate XQ locator and if you share it via PM I could make the necessary checks for you or you could check it yourself via the Buy Extra Baggage Allowance on the XQ website. That section would show your baggage allowance.
