Laidoff- filed h1 transfer on 58th day - stay in US

Hi Anil,
I was laid off from my old company on March 2020. Filed new H1B transfer with company B on 58th day of grace period and waiting for the receipt and decision. My i-94 is valid till 2021 .

  1. Am I eligible to stay in USA now?

  2. Would I be able to file another H1 transfer with company C before I get the decision on the H1B with company B? Do I need paystubs from Company B to file new H1 with company C?
