Can I put a 6oz jar in this size envelope?

I would recommend mailing a jar in a small box. Unfortunately it would not fit properly in this envelope. It would also break due to minimal protection.

Do these qualify to put stamp first class?

Yes - these can be used to ship First Class through the USPS as long as the total weight is under 13 ounces.

Could I get a pait of sock in these or do you know the Inside height when its sealed

Yes you can. Would work if you even had to fold them. The inside height when sealed is probably 7 inches
