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 osm.wiki/Tag:generator:method%3Dphotovoltaic. 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.

Hello! Quick question about the reference numbers with the operator (?) BREIHGO_CAR. Are there really 4 different operators that differ in name by a two-digit number? Or are these just an (internal) zone ID of an operator to define areas of use? This refers to the keys
gtfs:BREIHGO_CAR_22:stop_id
gtfs:BREIHGO_CAR_29:stop_id
gtfs:BREIHGO_CAR_35:stop_id
gtfs:BREIHGO_CAR_56:stop_id

In the latter case, I would recommend transferring this to an extra key.
gtfs:BREIHGO_CAR_22:stop_id=x would become
gtfs:BREIHGO_CAR:stop_id=x and
gtfs:BREIHGO_CAR:zone=22
