A note on Wiki says:
TCOM, TEXT, TOLY, TOPE, and TPE1 can contain multiple values separated by a foreslash ("/").
NOTE: ID3 v2.3 uses / as multiple artist separator, while v2.4 uses \\.

Having this song for example, tagged with MusicBrainz:

When I'm searching for Virtual Riot artist songs, this one does not appear. Instead, it appears as Virtual Riot feat. Varia artist, which is not just one, but two.

The TPE1 field is not separated with foreslash, but it exists a custom field Artists which contains all the artists tagged in this file.
In order to process Artists correctly and finding them, is it posible to priorize the Artists field first if exists, separate all the artists, and add them to the same song?

It's a huge can of worms you're currently trying to open.
ID3v2.3 says:

TPE1
The 'Lead artist(s)/Lead performer(s)/Soloist(s)/Performing group' is used for the main artist(s). They are seperated with the "/" character.

Since your song does not follow this scheme, it's not being parsed correctly, so: you should fix your song. That being said, I doubt the PHP's GetID3 library is parsing the "/" anyway as separate entities, so even if the file was good, Koel would not extract more than one artists from this song.

That's exactly related to a topic of another issue I've started, to change a song's model to support multiple artists. So for now, I doubt this could be fixed.
