Currently I have 3 120mm fans as intake in front and i have a kraken x61 that has 2 140mm in the radiator as exhaust well as a 140mm as exhaust. The case I have is a NZXT H440. Is 3 120mm as intake and 3 140mm as exhaust ok?

I have the PSU fan facing down and is intaking air from the outside.
The intake fans are: 3 stock NZXT H440 fans.
The exhaust fans are: Top Mounted kraken X61 liquid with 2 phanteks 140mm PH-F140MP_BK_PWM.
The Rear Exhaust fan is another Phanteks 140mm PH-F140XP_BK.

Sorry still new to building so it's all still pretty confusing.

What should i do to make this a positive airflow as well?

if you know the fan models you could look up the CFM rating to get an idea if they balance out.

sounds like you might have more exhaust than input.

if you have a psu sucking air from inside the case you can add that too, if it sucks from outside then ignore it.

a negative pressure system does work but tends to suck dust into crevasses. generally a positive pressure system (more air in than out) is suggested since it blows air out through the small cracks so only tends to pull dust in through the fans so can be filtered easier.
