Verify that you had removed the rubber plug and connected DP cable to DisplayPort-Out #6 (see picture below) and the other cable end is connecting to Acer monitor's DisplayPort-In. 

Verify in the Display Menu of Dell P2722HE, MST settings is ON.  See page 53 of User Manual.

I have connected my macbook to the dell monitor and it has output dp which i have connected to a predator monitor. Now i want to use the 2 screens as individual ones but now in my mac it is just showing the dell monitor during arranging window in displays and the same dell monitor display is being mirrored to the predator. but i want to extend but i dont have any where to configure to extend my predator as the display port from dell is going to predator.

Read the macOS support restrictions in, "FAQ Dell monitor and Apple".

The MST Daisy chain setup on Windows OS PC using USB-C would be the following, see page 34 =

Windows OS PC USB-C --> P2722HE USB-C to USB-C cable --> P2722HE #7 USB-C upstream port (Menu- Display--> MST On)
P2722HE #6 DP out port --> P2722HE DP to DP cable --> Second monitor DP in port

@DELL-Chris M​ 

Now i could able to connect DP out from Dell monitor to DP in to predator monitor.

but now the issue is, I am only seeing 2 displays to arrange in my macbook display.
one is Dell and one is main display of Macbook.

the 3rd one is just mirroring the dell montor and also it is not being showed in the mac displays.

so i need a fix for this .please.

my main motive of this screen is to extend the display not the screen mirroring

@balisaikiran​ As per the link I posted above, Dell cannot assist =

Most of the Dell D, E, G, P, S, SE, Alienware monitors have no Apple macOS support from Dell. This means your P2722HE.

* Go to the Apple Forum and enter your specific Dell monitor model in the top search bar. Read through any existing threads. If need be, start a new thread detailing your hardware and issue.
