Draw the Lewis dot structure for N. You would find one lone pair and three unpaired electrons.
When forming NH3 the hydrogen atoms pair their valence electrons with the three unpaired nitrogen electrons. So, NH3 has one lone pair.
Now, bring in a H+ atom (it has lost its electron [very irresponsible, by the way]) and it will bond with the lone pair left over on the NH3. Voila! No more lone pairs.

None. The only lone pair in :NH3 is taken up by H+ to form NH4+.

0 (zero)
all of the H are bonded by covalents with N
