S-Corp Health Insurance Reimbursement - ACA

We are a LLC filing as a S-Corp (1120S) - "Company A". My business partner has never had health insurance, so I was thinking it's important he and his wife has it especially now during Corona.
 
My family's current health insurance is tied to a different LLC filing as a S-Corp (1120S) - "Company B".
 
He did prefer / feel more comfortable that I moved mine over to Company A from Company B in 2020 so that our business would be handling both of our healthcare.
 
1. Can we have two S-Corp 2%+ owners having health insurance paid by Company A?
2. He saw he was eligible for an ACA plan. Is it ok for Company A to pay his ACA premium? Or does it have to be private insurance?
