I live in Pakistan and there is lowness of electricity in this country so first of all, there is a scheduled timing and I shut my PC down before that. But sometimes it can run out unexpectedly/unscheduled. And my PC is forced to shut down in just a second and I know it causes damage, my parents say I am not supposed to connect it to the UPS because it might cause damage to either of the things. Is there a way I can keep my PC safe even after power outages?

Sounds like your current UPS already damaged.

The rule of thumb is getting UPS twice the power of your entire setup. PSU wattage has nothing to with it. PSU just feeds wattage accordingly, granted its still within its written power ceiling. So, say you have roughly 220watts(low end-mainstream setups) you'd need PSU somewhere between 500-1000 watts.
How long the PSU can hold depends on your setup demands and the amount of time you have spend to charged its battery without load.

You need UPS with adequate wattage as your PC has. Preferably something than can support it to last at least 10minutes for you to properly shutting it down. UPS are fine to work with PCs. Don't worry. Again, that is as long as the wattage is adequate.

However, honestly, I have no clue about UPS branding quality. Maybe others can tell more about this.

I have an optiplex 755 so the default PSU that comes with it is 308 watts, I am getting a new PC next month and will have 400 watts in that one.
My UPS has 1000 watts, so will it be fine?
I have connected it but I shut it down immediately, but sometimes even when it's connected to the UPS, it would improperly shut down, is there a way to fix that?

I agree with most of the things that were said above... but may mention them again. First things first You WILL need a ups that can support your pc for a short time until you can safely shut down. Don't worry about your ups during power outages because that's what they are designed for. Seriously. Once power runs out battery kicks in. The only thing that would damage it is a power surge. If it isn't a higher end ups the more of a chance that it may fry itself if there ever is one. Just please make sure you buy the right one because they can get expensive. Especially if you buy the wrong one from a place that doesn't accept returns.
