As the address nodes have a complete address, it is not necessary to describe the building with the streets.

Please have a look on way/1081275914. What is the mean of the tags

I suspect that these are foreign keys from the data source that have already been completely transferred to the OSM database. Can these therefore be deleted?

Hello! Please notice this is a production database!

I remove the entry no address no building near near by -> possibly SPAM only

Welcome to OSM! Is this service every day on 10:45 or only Sundays? In this case you mist the shortcut Su before the time (we use the 24 hours notation)

Please have a look on noexit=*

Welcome to OSM! Please notice a name isn't a description. Please have a look on osm.wiki for a better description.

Done!

Cross-references to other wikis besides Wikipedia are rare, so I would rather suggest website = https://www.gem.wiki/Ajeel_Oil_and_Gas_Field_(Iraq).

The spelling with ref as a prefix has actually become established and allows a quicker assignment of the meaning of the key.

Hello! What is the mean of the tag ref:gem.wiki=Ajeel_Oil_and_Gas_Field_(Iraq) ?

Hello! You add the new key ave_ref to many relations. Did you mean ref:ave?

Can you please describe what you want to say with your import?
descripción = SOLAR
nombre = 435557
tipo = Solares y terrenos
Translated from Spanish to English your entries mean
description = SOLAR
name = 435557
type = Parcels and plots
Are these supposed to be solar cells? Then please read the Wiki article generator:method=photovoltaic. Numbers are usually not names (rather reference numbers, key ref). I can't think of a potential interpretation for the third key.
Does the dataset used for the import have an OSM-compatible licence?
If you need help, please feel free to get in touch.
