Yes, they do.
Different gases have different weight. It is because atoms of different gases have different Atomic Mass. It can be understood by the following example.
For example, there are two balloons (A and B) of equal capacity. Fill balloon A with 30,000 atoms of hydrogen and balloon B with 30,000 atoms of chlorine. Thus, balloon A is filled with hydrogen gas and balloon B with chlorine gas.
Now, calculate its mass:
Balloon A :
30,000 x 1 = 30,000 amu.
Balloon B :
30,000 x 35.5 = 1,065,000 amu.
Whereas, 30,000 is the number of atoms; 1 is the atomic mass of hydrogen atom; and 35.5 is the mass of chlorine atom. amu is used for atomic mass unit.
From the above mentioned we can assume that different gases have different weight.

Is the pressure exerted by different gases different?
Yes, the pressure exerted by different gases can be different, as it depends on factors such as the number of gas molecules, temperature, and volume. However, if the gases are in the same container at the same temperature, they will exert the same pressure.
How do gases behave under different pressures and different temperatures?
Gases behave differently at different pressures and temperatures. At low pressures, gases expand to fill the available space. At high pressures, gases become more compact. At low temperatures, gases condense into liquids or solids. At high temperatures, gases expand and exert greater pressure.
Are nonmetal and noble gases alike?
No. they are different.
Why inhaled gases is different from exhaled gases?
Inhaled gases is oxegen and exhaled gases you CAN'T brethe in because it's carbon dioxide.
Do gases of all types have similar physical properties?
Gases of all types have similar physical properties in the sense that they have low density, compressibility, and ability to expand to fill their container. However, different gases may have variations in their specific properties such as boiling point, melting point, and molecular weight.
