Install Unreal 1 version 227i or 227j. You can export everything through UnrealEd then and use it with anything, UT included.

Rename UPak.u because I assume you want to keep the contents intact from it and not use 227 version of the file which is normally installed with Unreal Gold version of the patch. Then try to load it in the UnrealED 2.1 or whatever and extract it via there one by one. If it has any errors, then further modifications have to be done. But otherwise you can try other programs like umodel or whatever the latest iteration is called, just keep in mind some of those programs produce errors. Another way is to not extract the models themselves but strip down the package until models are left using commands and "myleveling" tricks. So there are multiple ways possible all in all. 227i and above offers clean mesh exporting however.

I extracted the models using this program. But then it is impossible to compile UPak. u in UT with these models. many errors

You need to rename the files acording to the exec lines or change the exec lines to reflect the models.

It needs to find the path where the model is located, if the path is different or the filename is different(which happens a lot with unreal models), then you have to do some renaming..
