Does these songs exist? BB Sun, Javahn Spill etc

Here's some of the more unknown and vague possible unheard songs. I was wondering if we have more info on these songs, if they actually exist or have been confirmed as fake/never made.

Song 1:

In 2020 BB Sun tweeted out "remember that peep x harry fraud song we made together? where did it go" or something like that (Cannot find the tweet). I also remember him tweeting around the time Peep died that he was so excited to release it and it was the only thing he talked about it for months. Has it ever been debunked as not real?

Song 2:
There was a snippet of a song by Javahn Spill and a guy thought to be Peep that surfaced in 2022 and later got debunked as fake, and after that people seem to have forgotten about Spill and his collab announcment tweet from December, 2015 where he said "SPILL x LIL PEEP". What has happened to this song?

Song 3:

On Willie G's production called Bleach, Peep commented "mine" on it in 2015. Anyone know if he ever recorded on it?

Song 4:
Bbyfacekobe tweeted the day before Peep died that his friend had a unreleased Peep verse and a plu2o nash beat for sale. Do we have more info about it?
