In a scenario where there is a slip road and pedestrian island, which crossing ( Street Crossing 1 or Street Crossing 2 ) should have the crossing:island=yes tag? Or should both of them have it?

Neither. In your case, for each single crossing, there's no island in the middle of the road. See crossing:island for more info and a visual example of what crossing:island=yes is intended to represent.

Hi, thanks for your response! Then I guess the "island" in between the two crossings is not considered an island? What would it be called instead?

How about the "island" between https://www.openstreetmap.org/node/1083735850 and https://www.openstreetmap.org/node/1434767726 ?

Or, do you only mean that these are considered islands, as seen on the wiki page: https://nacto.org/wp-content/uploads/gallery/medianrefugeisland_3d/medianrefugeisland_parking_3d_0.jpg

The area between those two nodes is typically referred to as an island, but this is different from the OSM crossing:island. I'm not aware of an OSM tag that can be used to represent an island between two crossings like this. For an example of crossing:island, see here (sorry for the use of Google).

I would set it for none of the crossings.

I think the crossing:island=yes and crossing=island tags both are rather meant for the non-detailed mapping state where one road has not been split up into several highway objects in osm, one for each lane (example https://www.openstreetmap.org/node/496949296 ).

If you want to map the area of the traffic island do it like in this example: https://www.openstreetmap.org/way/390896480 (or one of the other tags mentioned on https://wiki.openstreetmap.org/wiki/Tag:landuse=traffic_island ).
