You didn't answer the question. I asked you how the Holy Spirit guides believers towards the Truth.
You did ??? Funny, I can't find this question in the text of your post that I responded to.
So I'll repeat: How does the Holy Spirit teach and guide the individual Protestant?
You're repeating this from where/when ???
But ... regardless, ... on to the question at hand ...
How does the Holy Spirit teach and guide the individual Protestant? ... Directly ... ?
The Holy Spirit can and does provide direct guidance to the individual christian, which the following scripture affirms ...
Romans 8:14 For as many as are led by the Spirit of God, they are the sons of God.
15 For ye have not received the spirit of bondage again to fear; but ye have received the Spirit of adoption, whereby we cry, Abba, Father.
16 The Spirit itself beareth witness with our spirit, that we are the children of God:

Then how do you explain the manifold Protestant believers who disagree with one another regarding doctrine, each claiming to be led by the Holy Spirit?
This is, most often, the result of believers' not seeking the Lord's truth directly, but rather choosing to listen to fallible leaders.
Unfortunately, these leaders also, often, are not listening closely enough or purely enough (i.e. without other egocentric agendas) to hear the teaching of the Holy Spirit undistorted.
In other words, ... rather than seeking for the truth of God, ... many are diverted by a desire to protect their turf.
I believe that it is much more profitable for us to humbly acknowledge our fallibility, ... to know that what we do know is by the grace of God, ... and to earnestly seek what further the Lord has for us as we grow in His grace.
James 1:5 If any of you lack wisdom, let him ask of God (note - not the church), that giveth to all men liberally, and upbraideth not; and it shall be given him.
