Yes, but the gauges are not that accurate. If there are no other issues you're fine.

Yes you will hear knocking, if the main bearing are shot and that's why you have low oil pressure, if it is the start of a bad pump or bad cam bearings or a plugged oil filter you will hear the lifters rattle first and if you don't do something to fix it you will soon have bad main bearing, THE GOOD NEW IS 25 IS FINE.

Oh, and from all I've been told or learned you need 20pis min., then 10 more psi per 1,000 rpms.
