Yes,
Boiling point of ammonia, NH3: - 33,34 0C
Boiling poit of methane, CH4: - 161,6 0C
Ammonia (NH3) has hydrogen bonding intermolecular forces, whereas methane (CH4) does not. In addition, ammonia is polar, and so also has dipole-dipole forces and methane does not. Thus, it takes more energy (higher temperature) to boil and melt ammonia than it does methane.
Indeed it can. At the boiling point liquid methane is in equilbrium with gaseous methane, so both exist simultaneously.
The boiling point of ammonia at atmospheric pressure is -33.34oC.
The meaning is at what temperature does ammonia melt at and what temperature does ammonia boil at? for eg. waters melting point is 0 degrees celcius and the boiling point of water is 100 degrees celsius
If you mean ammonia, the melting point of ammonia is −77.73 °C, and its boiling point is −33.34 °C. (Wikipedia)

Boiling point of NH3: -33,34 0C Boiling point of NF3: -129,1 0C The boiling point of ammonia is higher.
Metahne does not have a higher boiling point than methane. Fluoromethane, CH3F, has a boiling point of 195K, -78.2C, methane, CH4, has a boiling point of 109K approx -164 C. I make that fluoromethane has a higher temeprature boiling point than methane. This is what you would expect, London dispersion forces will be greater in CH3F as it has more electrons than CH4. CH3F is polar and there will be dipole dipole interactions which will not be present in CH4.

Ammonia: -33,34 0C Nitrogen trifluoride: -129 0C
At low pressure the boiling point is lowered and inverse.

Because of the hydrogen bonds in HCl and it's polarity. High polarity = high boiling point. All alkanes (methane) are nonpolar and have low boiling points. Alcohols and compounds with hydrogen bonding have higher boiling points because hydrogen bonds are very strong. Ask a chemistry teacher if you need a better explanation.
