Firstly, I understand your urgency as being under constant threat. However, I suggest you to be little patient. The difference of time betweeb above two of your posts is hardly over one hour, and you are blaming members? That's not fair!
Anyways. Here are your replies:
506(I) - When only a threat is given of dire consequences and to hurt. This is bailable and this is not your case.
506(II) - When threat is given to take away your life. This is non-bailable and this is again not your case.
Your case falls under 498A. However, if the complainant states in her complaint that you threatened her of taking her life then this section would be slapped.
Now, you original concern should be 498A and DV Act not 506(II). Though, in Delhi, now there is a stay on arrest in such cases, and police cannot arrest you directly but upon taking approval from concerned DCP, arrests can be made.
494IPC does not apply to Muslim as they are permitted multiple marriages by their personal law. However, second marriage by any Muslim is treated as a cruelity against the first wife and it creates a ground for divorce.
I hope your senses are satiated. I suggest you appoint an experienced lawyer who can get your case settled than to drag you to the court.
