Copy Paste Extended Tags

I applied various extended tags to an album like:
Record label
Date
and Unsynced Lyrics

I found a better quality of the songs and I just want to know if I can export the tags from the older album and import the tags to the better quality songs?

Yes, you can use the export function.
Or, if there are not too many, load the old and the new ones into MP3tag,
then select the old file(s)
use the function "Copy tags" in the files list context menu (right click)
select the new file(s)
use the function "Paste tags" in the files list context menu (right click)

if you have the same number and the same sequence of files for old and new ones, you can copy&paste in one go. When pasting the data from the first old file goes to the first of the new files, the data of the second of the old files to the second new file and so on.
