1. wfLoadExtension( 'PdfHandler' ); gives me an error while uploading PDF file.
2. wfLoadExtension( 'LastUserLogin' ); gives me an error to change or confirm email address.

What's the error? You have to give enough information about the kind of error you saw, otherwise no one can give you informed response.

@Ammarpad

1. PdfHandler = Unable to run external programs, proc_open() is disabled
2. LastUserLogin = CAS update failed on user_touched. The version of the user to be saved is older than the current version

When I delete them from LocalSetting I do not have these error

for the first one - seems pretty self explanatory. Fix your php.ini if you want to use pdfhandler.

For the second one, not sure, i would guess maybe that extension only works on older mediawiki.
