Если нужен адрес, то это addr:street + addr:housenumber

Hello
Are you sure that farmlands were abandoned? Some of them looks as it resting for a season
way/599055977 but it was 2-9 years ago

Also current date in "source" is almost useless, because everyone knows when changeset was created. More usefull will be bing's "capture date": right click on the background - last menu item "Show tile info" and "Metadata Capture Date" in the appeared window (it's better to write in yyyy-mm-dd format)

Hi
What is "under=1"?
http://overpass-turbo.eu/s/zJ8

If you want to add tag "name_1" you do something wrong: you should create 2 nodes for every POI
"Sklep odzieżowy" means "shop=clothes" with no name
Some useful links:
osm.wiki/One_feature,_one_OSM_element
shop=*
opening_hours=*

Hello and welcome to OSM
About some mistakes you do:
Don't ruin buildings. You need "building=retail" not "landuse=retail" and "shop=*". Especially you have "building:levels" on it
Don't put POI type into "name": Apteka "Witaminka" is just "name=Witaminka" because of "amenity=pharmacy"
Don't create node for POI if you put it on the building - either separate node or all on the building (if POI occupies the whole building)
If you create separate node for POI inside building don't double address if building has it
"opening_hours" is one tag, put all days into it

У нас используется нормальный порядок слов при именовании улиц, а не канцелярит: "Какая улица" и "улица Чья". Исключения в каждом городе свои, но их не много, обычно они упомянуты в разных городских постановлениях. Также можно смотреть как были именованы эти улицы на самих дорогах или соседних зданиях - в большинстве своём они уже написаны правильно

Hello
I think there must be two POI of Walgreens: chemist and pharmacy. And third one for Citibank's atm.

Hello
I think you did something wrong with third addresses:
node/5687980127 and others
addr3:housenumber=Friedjunggasse
addr3:housenumber_1=3
I think it must be
addr3:street=Friedjunggasse
addr3:housenumber=3

Hello

Hi
I have removed name:繁体中文 Dictionary says it is "Traditional Chinese", and there was name:zh already, so I dropped it
Besides OSM doesn't have hieroglyphs in popular tags
I haven't seen name:en-uk and I have no answer. It may depends on others name:s

I think you can use "ref" instead of HYDRANTNUMBER
emergency=fire_hydrant

Welcome!
You tagged building as BILDING=YES. We don't use capital letters in tags and values, and you have missed U
osm.wiki/Talk:Key:building
or just use preset - it make tagging easier
