I currently am losing water in the lines baseboardlines. One of my automatic pressure relief valves is leaking. Would it constantly leak until my boiler loses pressure/ water in the lines?

PRV is a different story. I'll have a video on it maybe later this week.
Assuming your system has a water line coming in, then it will continually refill any lost water and won't lose pressure. You can keep an eye on the leak and pressure gauge. If pressure is normal, then PRV is most likely leaking from scale buildup or seal not seated perfectly. Little drips each day are fine. How much is leaking?

Cool bro

[@rufiorufioo]

does it matter what type they are? I found that I have two air vents and one is 150 psi and other is type 67 35-50 psi depending on brand... ?

That should be the maximum operating pressure. So if you have a lower water pressure system either would work fine.
