Can you please run:
sudo apt-get update && sudo apt-get dist-upgrade && apt-get -f install
If that does not work, you may need to downgrade perl-base:
sudo apt install -f perl-base=5.22.1-9
Then run sudo apt install -y git

Shouldn't be seeing these if you used sudo.
Given what I have seen from your apt-update print out, your sources.list should be ok. But may need to check it later if the problem persists.
Installing git from repo should work fine, first time.
Can you try
sudo apt full-upgrade
sudo apt install git
sudo apt --fix-broken install
Let's try installing liberror-perl from a .deb package first, then try installing git normally in the terminal again after:
http://archive.ubuntu.com/ubuntu/pool/main/libe/liberror-perl/liberror-perl_0.17029-1_all.deb
sudo apt install git
also my softwere store not working well., it can't able to use internet ,
most of the time it's keep loading , anything i search on them , also my net speed is totally fine
you can see i hv uploaded screen recording on google drive :-

how to install "deb" from terminal
Click the link and it will give a pop up offering the .deb package. You can either select to Open With Gdebi and run the installer, or you can save the package in Downloads folder, then Double-Click it to run the installer. Once installed, then try installing git again in the terminal.
Yes, your above details from running commands in terminal showed repeated failures in the updates, too.
And git should install from terminal normally without dependency errors.
You may try
pkill snap-store
pkill gnome-software
Reinitialize and test Software store
yes i did this , it takes me to the software store , and there store keeps loading
Ok, select to Open with Gdebi, instead.
Heh...
sudo apt install gdebi

may be it is installed now?
That'll do it. Ok... So, what happens with installing git now?
Have you
pkill gnome-software
and then reopened it?
yes , i did
Opening Software & Updates, first tab Zorin Software; Download From -is this set to Main Server?
yesss

finding best server ,
may be i have to change right?

which one ? i'm in india

I would highly recommend staying to "Main Server." The "best server (Local region)" option has never worked the way it should.
You are showing a variety of symptoms.
Git not installing properly (on my machine, there was no problem locating and installing liberror-perl), software store constantly loading and updating sources.list was dropping connection above, too.
Like git, cmake should have had no trouble installing, as well.
There seems to be a larger problem.
You may clean your apt cache, remove the ~/.local/share/gnome-software file if it exists and
These suggest packet loss or net drop.
This suggests that Synaptic Package Manager was open and running while also running apt/dpkg in terminal.
