Your buildings you drew look good! I went ahead and changed them to building=yes and removed the amenity=school. Also, personal information in changeset comments isn't necessary, but that's a personal privacy choice.

Adding the coffee stand is useful -- does it have a name? Also, looks like an optional tag you could add on this one is also takeaway=only

Oh, and also would remove the amenity=school tag here, since the building does not house a school. (The grounds which surround it are already tagged with the amenity tag, which is more correct.)

The tagging looks pretty good! Only suggestion is to use the squaring tool (iD shortcut 'q') and make the corners more closely match the imagery.

Hi, have a few review comments about house tagging, descriptive names, and the outline, but pretty wordy, so will send it separately!

Yes, just removing old tags is usually the best method - but there is a way to add info to tagging keys to indicate status if really necessary. It’s described here, would suggest using sparingly: osm.wiki/Lifecycle_prefix

If you could, give it a try! Thanks again.

Also, the OSM convention is to place the school details (name, address, etc) on the school grounds rather than the building. (See amenity=school) Most of the tags you added were already tagged that way. So I'd suggest removing the non-building specific tags, and placing them on the grounds instead.

Hi, welcome to OSM! Thanks for editing. A few comments: Adding the building is appreciated, though the outline should be followed more closely, and each individual building mapped separately.

Hi again, this is a useful edit, I just followed up to change it from a amenity=kindergarten tag to a more accurate leisure=playground with access=private as documented here (amenity=kindergarten). Keep at it, it may take a few edits to learn the ropes, but mapping is fun! Thanks again.

Welcome to OSM! Nice job! Looks great.

Hi, thanks for the edits! Have to ask though -- is the building and address for the closed business still there? It's possible to remove just the business tags (name, type, phone, website, etc) and leave the still-valid feature for the next tenant. (I've already put it back, but lmk if indeed the building's gone!) Thanks again, hope to see more.

Hi, welcome to OSM and thanks for the edits!
First, I changed the generic “name” tag to match the “name:en” you added (your editor didn’t show you the (name in local language tag, it seemed.) Also, please save your changes before jumping a large distance between edits - helps to keep them local. Thanks again for editing!

Hi, thanks for the edits - looking at a few of them, please check if features are already mapped before adding another. (The Starbucks coffee shop and Jack in the Box in recent edits were already there as nodes.) Thanks again!

The aerial imagery does look shifted from the data in this area, so if drawing new buildings or reviewing the existing ones, would suggest first aligning the imagery with the existing buildings ('B' button in the iD editor to open the panel, then dragging on the gray box at the bottom to align) so everything is at least consistent in the immediate area. Thanks!

Hi, welcome to OSM and thanks for the change! Upon review, not sure what your changeset comment means. Does that backyard building no longer exist, or was it drawn incorrectly? It looked pretty reasonable, though shifted.

Thanks for the concern, but don't worry about it - it was just one change, and it's already fixed - was just letting you know in case there was an OSM misunderstanding or process error. Glad the map is helpful for your project!

Hi, it looks like you may have accidentally renamed the park instead of the tree. :) Not a problem, I've already changed it back -- also, it looks like you were tagging a tree's reference number; I'd suggest adding a "ref=22" tag to the tree instead of giving it a descriptive name. Cheers!

Hi, welcome to OSM and thanks for the edits! I adjusted your edits a little bit -- in the school street address, the OSM convention is to try to expand the abbreviations there; also, the school grounds were already named, so no need to add the name to the building too, in this case. Thanks again!
