Will the rights of the girls whom the questioner deceived and promised to marry in order to fulfill his desires, and the right of the girl whom he married customarily for years and then abandoned, remain suspended on his neck until the Day of Judgment, and what should he do now?

You must offer sincere repentance for your past sins with these girls. What you called an "Urfi marriage" is void due to the absence of a guardian (wali) and witnesses, and it must be annulled. No mahr (dower) or mut'ah (consolatory gift) is due from it, as the contract itself is فاسد (void/corrupt).
