1) Upper Zakhum is either paraffinic or paraffinic-naphthenic, depending on what you like to believe. See ternary diagram.
Of the others you mention I don't have paraffin/naphthene/aromatics content so I don't know whether they are officially to be called paraffinic or not.
2) We don't know what assays you have, so we have no opinion about them.
The Upper Zakhum assay that I posted is from ExxonMobil. You may have heard of them. They are an American oil company. The biggest in the world. They are not amateurs.
3) Such a detailed crude assay is suspect as it is probably computer generated from the few product fractions of a real crude assay. In that case the properties (pour point, cloud point, SARA) of each pseudocomponent were generated using dubious correlations that have low accuracy.
But even then: if you don't have the paraffinic content of a crude oil then you can't say whether it is paraffinic or not. That should be obvious.
4) High API gravity is often, but not always, an indication of paraffinic crude. A light crude, with not much residue in it, will have a high API even if it is not paraffinic.
Moreover one paraffinic crude may have mainly light paraffins with a low pour point, while another paraffinic crude may have more heavy paraffins with a high pour point. So two crudes with the same amount of paraffins but with a different light/heavy paraffin ratio will have different PP.
Also normal-paraffins have a much higher pour point than iso-paraffins, so two crudes with the same amount of paraffins but with a different normal/iso ratio will have different PP.
Also the rest of the crude plays a role in the value of the PP, so two crudes with the same amount of paraffins but with a different naphthenes/aromatics ratio will have different PP.
5) The crude oil UOP-K is not a reliable indicator of type of crude, unless it has an extreme value like 12.5 or below 11.
In any case to calculate the UOP-K you need to use the Mean Average Boiling Point (MeABP) of the whole crude which is to be calculated from whole crude ASTM distillation data, not TBP data. Check API technical databook and GPSA engineering databook.
