1. evaportation is easier as vapor pressure increases right? if not, than what is the correlation

Yes. The pressure exerted by a vapor escaping from a liquid. It quantifies the tendency of molecules to enter the gaseous phase.
With liquid water, as the temperature of the water increases, the vapor pressure increases. When the vapor pressure reaches ambient atmospheric pressure, the water boils.
In terms of comparing different liquids, Diethyl ether has a higher vapor pressure at 25 degrees Celsius than Ethanol does. Ethanol has a higher vapor pressure than water.
Ether evaporates faster than alcohol which evaporates faster than water.

When vapor pressure increases, evaporation increases.

Volitile compounds are defined as those with a low vapor pressure... They evaporate very quickly.
But if you are talking about a single liquid, the vapor pressure is increasing as you start to boil it off...
I'm not sure which case applies to your question

yes, that is correct. as vapor pressure increases, this means the liquid is more voliatile and more molecules are evaporating per unit time.
