Project ended when H1B Transfer in Progress and 60 day grace period eligibility

[awrftp]

I was employed with Company A in H1B until 18th Sep 2017 with a approved petition and I94 valid till 17 May 2018. I joined Company B and did H1B transfer on 23th Sep 2017. This H1B transfer is still in progress. But the project that I was working with Company B has ended on Jan 29th 2018.

My previous employer "A" has revoked my petition already and also my current employer "B" will revoke my "in progress" H1B transfer petition soon. I have below questions.

1. If my employer B revokes the petition, will I be immediately going out of status ? or When I will be out of status ?
2. Do I still have 60 days grace period from Jan 29th, even though my H1B transfer petition is not approved ? 
3. Since I have a valid I94 till May 2018, can I still do another H1B transfer within this period ? 
4. If yes, what are the chances that it gets approved or goes to consular processing ?
5. Is there a timeline before which I need to do another H1B transfer in regular processing, instead of doing it in consular processing ?
6. When do i need to go out of the country ?

The 60 day grace period started when you left the old employer. There is no new grace period from the new employer because that H1 isn't approved.

You used your one time 60 days grace period when you took 5 days break between leaving first employer on 18th Sep and joining the second employer on 23rd Sep. Now since you do not have H1b transfer approved yet, you do not get a new 60 days grace period.
