The 'output' I want after working on the patterns can be seen on this cleaned images(I have marked the output with 'red' color):
I really want to know how to do so.
The pattern is the screentone and if you want to preserve it, there are some ways to go about it.
You can forgo using filters on the page. That means no Denoise/Topaz/whatever it's called. Use manual cleaning methods like leveling, brush tools, dodge/burn tools, etc. Technically it should be possible to tone down the settings on the filters so they aren't so overwhelming, but I've never used them so I wouldn't know how.
If you don't want to forgo the filters altogether, there's something else you can do. To preserve tones and details, select them with the Select Tool or the Lasso Tool (any) or the Quickmask tool. This will allow you to work on the rest of the page separately, so you can, for example, level the main page like crazy and go easy on the selected parts, or vice versa.
That way you can select the parts you don't want filtered, filter around them, then manually clean your selection afterwards. Might be a bit difficult getting the result to look uniform and not patchy, but it might be worth trying.
Alternatively you can manually reapply the screentone if you can find a matching pattern, but as you can imagine this is an incredible amount of work rarely worth bothering with. Certainly not for bad raws like this.

Weekly pages are ugly. The printing is occasionally uneven and even if it's not, the quality and coloring of the pages themselves (at least in Jump) makes preserving the patterns an impossible dream. Your best bet is to either replace them entirely, or just wait for a much higher-quality printing in the volumes.
If you insist on trying, first you have to stop using filters. In fact, everyone needs to stop doing that. I'll give you a minute to uninstall them.
Okay. Next, you need to level in small steps. Instead of one big jump, take several smaller ones before you resize the page. It may require one afterwards, too. Once you do, go over the pattern with the clone brush where needed, using a good section as your home point. Try to line it up as well, so you don't break the repeating pattern. Mind the gradient, as most patterns in the background fade to black or white.
