OP is still @HemanthJabalpuri I did those tests while I was in the need for a emu as I didn't have a working phone at that time. I'll take a look at it and update but might not be for a little bit while, a week or so perhaps.
Safetynet can't be passed unfortunately. For that you not just need magisk modules to be working for one, but riru too probably. Unless someone can make a safetynet patch for android nougat exclusively.
Xposed can be installed both on x86 and x86_64 versions, see OP. Hemanth has described it pretty clearly, but alas, installing xposed that way would probably kill any chance to bypass safetynet.
No magiskhide isn't working. And no, Edxposed module can't be installed. Correct me if I am wrong, but Edxposed, Riru and LSposed are Oreo and above, no chance for nougat unless someone eclusively works on it for emulators only.
