I've heard different accounts about that.  Some say 7, others say 3.
I don't know if it was mentioned in the mission transcripts.  Maybe I
should check my copies.

Had the landing bag been deployed, it wouldn't have mattered how long
Glenn had stayed in orbit.

You might be right, but the Mercury astronauts were trained for
landing anywhere, just in case.

I believe the Indian Ocean tracking ships came later, starting with Gemini.

That was part of the mission rules.  Once Armstrong activated them,
the flight was over and the crew had to return as soon as possible.

All that happened out of communication range. When

I believe that the flight director on duty at the time, John Hodges,
selected the South China Sea site.  It was an auxiliary location, so
there wouldn't have been a full recovery force on hand, but it was
within reach of any ships in the area.  Part of that might have been
because the base at Subic Bay, plus the presence of the USN in the
Gulf of Tonkin.

The crew had to wait several

One thing that nobody counted on was the sea state.  The account I
heard was that even Armstrong became queasy.
