When the applicant fails to accurately or completely report travel history, the big issue is whether or not the applicant still meets the physical presence requirements after corrections are made. You state you still met the 1095 days credit threshold to qualify for a grant of citizenship, after correcting your travel history, so this application is still viable, assuming of course that you meet all the other requirements.
The next big question is to what extent the discrepancy between what was submitted and what was in error raises questions about the applicant's credibility, the extent to which the applicant can be relied on to be an accurate reporter of the facts. In this, whether the omissions are apparently due to error, or appear to be misrepresentation, can loom large. Hard to judge this, other than realizing that IRCC is well aware that citizenship applicants make mistakes.
Whether or not to withdraw the application and re-apply, given that you meet the presence requirement (if short, there is no doubt, the best approach is to withdraw and re-apply), is a more personal and, depending on the circumstances, potentially difficult decision. That said, if you are considering withdrawing, it would be a good idea to respond to the request, acknowledge the mistakes made, provide an updated and FULLY corrected physical presence calculation, and passport stamp translations, BEFORE withdrawing.
Key factor in your decision making is the scope of the errors and omissions made, including the impact on the physical presence total credit. Others have reported NO problems despite making mistakes of three weeks or more WHEN they applied with a good margin over the minimum, enough to still have a good margin over the minimum after correction for omissions.
But, basically, if other than a minor mistake, or two, the application is solid, and there is no reason to apprehend that IRCC might have serious credibility concerns, should be OK to stick with the current application. That said, mistakes, no matter how innocent, compromise a person's credibility at least to the extent it indicates the applicant is not an entirely reliable reporter of facts. In contrast, if evasion or deception are suspected, that can severely undermine the case. And, it warrants noting, it is to help quash any concerns about this that makes following through and fully responding to the request a good idea.
In this latter regard, there can be a big difference in how things go after withdrawing and re-applying. Many times this will result in the second application easily sailing through the process, largely due to the combination of the first and second application amply shows the PR meets the requirements. But if IRCC has substantial credibility concerns based on the first application, that could lead to elevated scrutiny of the second application and non-routine processing potentially involving lengthy delays in the processing timeline.
SO . . .
1-Do all applicants needs to submit scan of their passport or just biometric page and later agent will determine if scan is necessary ?
Not all applicants will need to submit copy of all passport pages. Many will.
2-How it is possible to translate all stamps? i have many stamps in many languages, should i go to 10 diffrent translators ?
Well, anything that is in a known language and is legible can be translated. How many different translators might be needed will of course depend on the actual languages in the passport stamps. Probably best to search for a reputable translator with significant experience in providing translations to IRCC and in addition to using their services to the extent they can translate what you have, consult with them about how to approach this with the other stamps that they cannot translate.
3-I'm thinking to withdraw my application and submit again, due to the fact that i did not delare all my travels it might raise question on why i failed to declare on time , is that right thing to do ?
Again, as long as after FULLY correcting the travel history, you clearly still meet the presence requirement, this is a personal decision . . . as I discuss above.
