The output of cat /etc/modprobe.d/linux515-broadcom-wl.conf is

blacklist b43
blacklist b43legacy
blacklist ssb
blacklist bcm43xx
blacklist brcm80211
blacklist brcmfmac
blacklist brcmsmac
blacklist bcma
23

its the same, so you can remove it:
sudo rm /etc/modprobe.d/blacklist.conf
also uninstall everything:

sudo pacman -R linux515-broadcom-wl linux54-broadcom-wl linux515-headers linux54-headers

reboot
and post output from:
inxi -xN
ls /etc/modprobe.d

24

When I try to uninstall using the command you gave this comes

checking dependencies...
error: failed to prepare transaction (could not satisfy dependencies)
:: removing linux515-headers breaks dependency 'linux-headers' required by rtl8821ce-dkms-git
25

why do you have it installed? its for rtl8821ce card, which you dont have…
post output from:
pacman -Qs dkms

26

The output of pacman -Qs dkms is

local/dkms 3.0.6-1
    Dynamic Kernel Modules System
local/rtl8821ce-dkms-git 1.0.5.r140.gbe733dc-1
    rtl8821CE driver with firmware
local/rtw89-dkms-git 1:r178.f3ea327-1
    Driver for Realtek 8852AE, an 802.11ax device
27

so why do you have it installed? you dont have this card

28

I don’t know maybe i installed when I was trying the methods of other forms

29

you have also installed rtw89-dkms-git, which you also dont have…
remove it all:
pamac remove rtl8821ce-dkms-git rtw89-dkms-git
then:

sudo pacman -R linux515-broadcom-wl linux54-broadcom-wl linux515-headers linux54-headers

reboot
and post output from:
inxi -xN
ls /etc/modprobe.d

30

The output of inxi -xN is

The output of ls /etc/modprobe.d is

hp.conf  r8169_blacklist.conf
31

just to be sure, post output from:
pamac list -qm

32

The output of pamac list -qm is

easywifi-git
33

remove it too, you dont have a working wifi anyway:
pamac remove easywifi-git
then reboot
and try installing again the drivers:
sudo mhwd -i pci network-broadcom-wl
if you dont get the same error, reboot

34

Still got the same error

35

I just noticed that before in the network section I had a wifi and airplane mode options but now it is not there

36

i dont know whats heppening here… are you dualbooting with windows?
post output from:
find /lib/modules/ -name "wl"
sudo dmesg | grep wl
pacman -Qs manjaro-firmware

37

No I am not dual booting, I deleted windows and installed Manjaro
There is no output for find /lib/modules/ -name "wl" and sudo dmesg | grep wl
The output for pacman -Qs manjaro-firmware is

local/manjaro-firmware 20160419-1
    Extra firmwares for Manjaro Linux
38

what is the output from this:
sudo mhwd -r pci network-broadcom-wl

39

The output for sudo mhwd -r pci network-broadcom-wl is
