Can you please tell me which permissible scatter in sensitivity can be between a pair of tweeters? For example, on Twitters Dayton indicated 89 0.2 and 89 0.4 This can be considered a selected pair? Or for example 89 0.2 and 88 0.4 This can be considered a selected pair?
If you mean you are comparing 89.2 dB with 88.4 dB, then I would regard this as a reasonably matched pair.
There will be more variation in the crossover components.

If there is a series resistor to adjust level, this can be also used to compensate for sensitivity differences.
The change in resistor value would probably be small enough that the high pass capacitor need not change.

Circuits can always be trimmed, but most builders would not bother. You'd also need good test
equipment for measuring drivers.

I would like whether the crossover would be the same for both tweeters.
What is the maximum permissive difference between tweeters in sensitivity, so as not to make changes to the crossover for each of them?

Differences in sensitivity between two examples of the same tweeter are not normally discussed here as the manufacturer will hold these differences within acceptable limits.
It may be that you are worrying unduly.
Can you give a link to where you are getting the selected pair information?

On tweeters there is a sticker. It is difficult to find absolutely the same pair . I have a few but they all differ. I am about it.

Unless all the components in your crossover are better than 10% in tolerance, any pairing
of the tweeters should work well. The mounting and baffle will also affect the driver response.

There should not be a problem with tweeters of the same model.

Thanks for the corrected image.
You may pair up any of the tweeters that tick any of those little boxes.
If you have a few, then match them as closely as you can and stop worrying about it.
