You can get one 30 day extension, yes. After that you're at the mercy of the unable to travel due to covid extension or finding another way to prolong your stay here if you choose to do so.

You can report up to 7 days late and not be fined. After that it's 2,000 baht whether you're 1 day over or 1 year over.

Doesn't sound like it

Depends which visas your friend is eligible for.

I believe the 7 days Phuket then transfer to Samui has been knocked on the head for the time being.

They're closed today and Wednesday this week.

Where are you flying in from?

Fly in from overseas yes, and pick up yes.

For the Cambodian on the covid extension, provided the immigration office is willing to convert in country and his prospective employer can meet the additional requirements of applying in country then yes it can be converted to a non-B. However, I am not sure if there are additional rules for migrant workers, of which Cambodians are considered.

For the Iranian on a volunteer visa, was this obtained by actually volunteering or by an agency giving a big brown envelope to an immigration officer in the middle of nowhere?

a lot of airlines have said they're cancelling all flights starting tomorrow, not just those in and out of dark red zones.
