"Very probably the Debrecen II stamps were not allowed to be franked. Near all items with these stamps are either philatelic (CTO) or with the stamps being used as additions (something like a label) (Dan Grecu)" link "Complete forgeries exist of this issue and are often found In large multiples or even complete sheets."(Scott)
I hope @falshung can confirm if these are forgeries or not.
Decent examples of genuine stamps are now almost impossible to find on auction sites. Anyone who wants to donate - please do
First the original post by rod222, the postage dues appear to be genuine, the Segely-belyeg are forgeries Why? - if/when I do an article I will elaborate
Very little info is available on the Debrecen 2 series as opposed to the Transylvania or the Cluj series. The traits to define genuine vs. fakes are not always clear. The forgeries probably made in Paris are VERY good

First thing to check is the inner part of the circle to the right of the large blob. There should be some small inward protrusions and/or a fuzzy area. Overall the lettering and the circle itself are not very sharp while in the forgeries they are well defined. There are some minor details but the mountains in the circle show well defined unbroken lines as opposed to the forgery. There are other lines and breaks in that area that do not match.
Here again we check the circle for protrusions and overall appearance In the bottom corners of the genuine we have a large blob with a large dot below it. The forgery has a well defined area with a small dot.
Added note - I believe any fakes are full forgeries, both the stamp and the overprint. Genuine stamps with no overprints do exist but were proofs or essays The stamps exist as inverts, double and triple overprints but these were probably made "for collectors" not as errors Forgeries are often found as multiples, blocks and even full sheets. Forgery paper may have a yellowish tinge some are on very white paper
