Please do not invent your own tags like that and first check out if something else is being used.

Are you saying these are steps? If so, please use highway=steps:
highway=steps

In particular:
- way/532217647
- way/532217646
- way/532216545
.
These are all marked as crossings, but they seem pretty long for crossings.

Do you think it's now safe to remove FIXME from way/94632235?

Please see this for an example of good crossing tagging: osm.org/#map=19/32.68811/35.06434

Are you sure these are crossings and not normal footways? A crossing is typically short and for crossing a street (מעבר חציה).

crossing=*

There's a problem with the gym: It has name="אולם הספורט"
.
Hebrew name: "בריכת השחיה"

You should change name:he to
.
אולם הספורט

Please do not add personal houses to the map. This is a public map. Everyone can see your edits.

If you want to save your house on your phone, You can use the Maps.ME Bookmarks feature.

I've deleted the house you added.

I think you need to add name="תצפית מפל תמרים"

Please ignore the above comment. I see there was a followup changeset.

Hello,
.
You forgot to update name:he

What would the right tag be? It's not image, and website is already occupied.

I don't think it's useful. I'll fix this.

Do you think it's useful?

I think you should be using "website" rather than "image". But let's wait for @SomeoneElse's reply. He knows better.

Welcome to OSM. It's advised to do perfectly square buildings. Click the building, then click the "square" button

ברוכים הבאים ל OSM!

מומלץ לעשות מרובעים מושלמים. ניתן לישר את הזוויות על ידי לחיצה על הבניין ואז לחיצה על Square

I tagged this as "man_made=water_tower"

Hello. You accidentally put all the tags on a node and not on an area. Fixed in: changeset/52901986

Those are tricky to tag. I wonder how the others are tagged.
