exam one is who is calling

This is a follow up for Life Insurance Applications by Lincoln Benefit Life Ins. Company.  They might identify themselves as part of the agent/company that signed you up, for example Allstate, State Farm etc..
This is part of the interview process when applying for Life Insurance.

This is Exam1 which is a paramedical company hired by insurance companies to complete a brief telephone interview or 'tele-underwriting' call, prior to issuing life insurance on behalf of the life insurance company. If you applied for life insurance, you'll want to take this call, or your policy cannot be issued.

Who is the owner?

This is the Knights of Columbus insurance confirmation number for new policy verifications.

Received a call from this number.  Appears to be a central service for insurance reviews.  In this case, the call was valid as I recently applied for insurance and the caller identified himself as being with State Farm, my agent.

If you recently fill for life insurance they call u after medical check up to a small interview about u lifestyle.

This is from Lincoln Benefit Life Insurance

Caller identified herself as working for State Farm Life insurance.  I did not apply for any coverage.  The # she told me to call back at was 877-222-1754. Google says that call # is for State Farm International.   Don't mess with anything international.
