Always,
A.C meters in R.M.S ------- voltage,current
D.C meters in AVG ----- voltage and current
But power is AVG value in A.C AND D.C.

This is true only if the meter is a true RMS meter, otherwise this is false.

Voltage to be measure is in rms peak to peak consider in calculation.

In ac circuit there is a voltage is display on voltmeter rms(root mean square). It shows the equal values of dc and ac sources.

I think it's peak or peak to peak.
