Sometimes a clef has the number 8 below it, which indicates that the notes are to be played one octave lower than written. It can be used with treble clef for people who are unfamiliar with bass clef, or in bass clef to avoid excess ledger lines.
Yes
that all the notes should be treated as an octave lower :)
Double Basses normally play in the Bass Clef. On the other hand, they sometimes use Tenor Clef and I have seen Treble clef used for higher notes but transposed an octave lower than written.
They both play in treble clef. Alto plays in the key of E flat, and tenor plays in the key of B flat.
the guitar plays on the G, or treble, clef. It plays transposed down an octave, though, so it could technically play untransposed on a bass clef. All guitar music is written in the treble clef, though.

The treble clef represents the octave above middle C in music notation.
The purpose of the octave clef in music notation is to indicate that the notes written on the staff should be played or sung one octave higher or lower than written.
The range of notes in the bass clef octave typically spans from the F below middle C to the E above middle C.
The octave treble clef is significant in music notation because it indicates that the notes written on the staff are one octave higher than they would be with a regular treble clef. This allows musicians to read and play music that spans a wider range of pitches.
To notate a musical passage for a lower pitch range using the treble clef octave down, you can simply add an ottava bassa (8va bassa) notation above the passage. This indicates that the notes should be played one octave lower than written on the treble clef staff.
The treble clef octave in music notation is significant because it indicates the range of notes that can be played or sung by instruments or voices that use the treble clef. It helps musicians read and interpret music accurately by showing the specific pitches within a certain range.
To write an octave higher, you simply transpose the notes up by eight scale degrees. For example, if you have a C note in the bass clef, you would move it to the C note in the treble clef, which is one octave higher. In terms of notation, if you start with the note C4 (middle C), an octave higher would be C5. This can be represented as: C4 → C5.
