Hi!
The tag highway=emergency is rarely used,
I assume you meant area:highway ?
See osm.wiki/Proposed_features/Street_area#traffic_island

Hi!
Please review typo highway=emergency + area=yes
Maybe you meant area:highway=emergency?

Hi!
Please review typo highway=er on
way/10852908
way/10852904
Did you mean service?

Hi and welcome to OSM!
Please review typo highway=6 on several
barrier=fence. I guess you meant height=6 ?

If you want to map the area please don't use highway. You may use area:highway=footway for this.

Hi!
There is no need to draw a polygon to map a sidewalk, you can simply add
sidewalk=* tag to the corresponding highway=residential.
Example:
Instead of way/522955616
you can split way way/23067832 at node node/633212855
and add sidewalk=right to the eastern part.

I think I was able to restore most of the data deleted data, so I hope the remaining damage is very small :-)

See changeset/51872135
and
changeset/51873009

I've restored the wetland way
way/376234910
(you accidentially removed the tags before
in changeset/51836900)
I am not sure if you removed this bridge
way/362580439/history
accidentially or not?

I've reverted this changeset.

changeset/51836900
Please be very careful when deleting ways which belong to relations.

I've also managed to restore the tags of most of the other objects, see changeset/51870822

I've reverted the changes to the relations, see
changeset/51870499

Hi and welcome to OSM!
You changed a lot of complex relations here
so that they have no tags. I assume that was not intended?

Hi and welcome to OSM!
Why did you change contstruction=rail to highway=rail ?
When construction is finished you can simply remove the construction tag.

Hi and welcome to OSM!
The tag highway=projected is only used here. Please check if osm.wiki/Lifecycle_prefix
helps to find a common tag

Hi!
I've noticed that you sometimes used addr:street instead of name. Is this intended?
way/404122641
way/404122634
way/404122616

Moin!
Schau mal bitte auf way/164036190
Du hast hier name=Seestraße auf
addr:street=Seestraße geändert.
Ich finde addr:street=Seestraße an mehreren Straßen, wahrscheinlich ein Versehen?
Abgesehen davon sieht o.g. Weg mehr nach unclassified aus.

Hi and welcome to OSM!
I've noticed that you mapped some residential roads here. That is good :-)
Two problems:
1) When mapping highways you should not use any tags with the addr: prefix.
Use postal_code instead of addr:postcode, use is_in:city instead of addr:city
2) The name of the city is Kakinada, not
KAKINADA or kakinada, Please make sure to use the correct spelling.
3) Many ways have the tag addr:street=PRATAPNAGAR or addr:street=pratapnagar
and a few more spelling variants.
What does that mean?
It is obviously not the name of a road.

I've corrected problems 1) and 2) , see
changeset/51868911

I see you started to fix them. Please review footway
way/371314770
If you don't plan to map all sidewalks as separate ways I suggest to remove it and add a sidewalk=left to (a part of) the major road. See also
sidewalk=*
