I have tried following things, and im beginner with ubuntu so afraid to make some changes in firmware or booting sequence might go something wrong please help me.

$ systemd-analyze
   Startup finished in 3.752s (firmware) + 4.733s (loader) + 37.788s (kernel) + 1min 27.819s (userspace) = 2min 14.094s
    graphical.target reached after 1min 25.853s in userspace

It looks like TeamViewer is taking up a lot of your boot time. I'd suggest disabling its ability to start at boot or outright using sudo apt remove on it. Snaps slow down system performance a lot, if you do not use snaps I would suggest removing it (though this is dangerous if you run GNOME, I only advocate it if you run xfce, lde or kde)

EDIT: I've talked with a few tech friends of mine, you seem to have A LOT of snaps. Start getting in the habit of installing .deb files or using apt instead of snap all the time. Snap volumes are loaded in dev-loop files, which you have a lot of that take up a lot of time. Try removing some snaps and using the repos or .deb instead
