3 eighth notes equal one dotted quarter note
No. One eighth note equals one eighth of a whole note. Two eighth notes equal a quarter note, and four quarter notes make one whole note.
I believe the quarter note equals 42, but I'm not really sure.
At simple time signatures, a quarter note takes one beat. In compound time signatures, a dotted quarter note is equal to one beat. In cut time or alla breve time, a single beat is a half note.
Four quarter notes is equal to one whole note (the empty note head with no stem). One whole note is held for four beats. Four quarter noes is also equal to two half notes (the empty note head with a stem). Each half note is equal to two quarter notes. To put it another way: one half note is worth twice the value of a quarter note. Four quarter notes is also equal to eight eighth notes (the filled note heads with flags). Each eighth note is worth half of the value of one quarter note. Four quarter notes is also equal to sixteen sixteenth notes (filled note heads with two flags). Each sixteenth note is worth half of the value of the eighth note or one fourth of one quarter note. Those are the most common divisions of four quarter notes. You can also mix and match those divisions; for example, four quarter notes takes up the same amount of time as one half note plus one quarter note plus two eighth notes. There are hundreds of thousands of configurations that could rewrite the value of those four quarter notes, which is just one reason why there is so much variation in the types of music it is possible to write!
1 quarter-note.
3 eighth notes equal one dotted quarter note
No. One eighth note equals one eighth of a whole note. Two eighth notes equal a quarter note, and four quarter notes make one whole note.
I believe the quarter note equals 42, but I'm not really sure.
3 quarter notes equal one dotted half note. A quarter note is one beat, and a dotted half note is three beats, so there are 3 quarter notes in a dotted half note.
two eighth notes
Actually, 2 quarter notes equal one half note.
At simple time signatures, a quarter note takes one beat. In compound time signatures, a dotted quarter note is equal to one beat. In cut time or alla breve time, a single beat is a half note.

A whole note.
A quarter note is equal to 1 beat. A half note is equal to 2 beats. Therefore, two half notes are equal to 2 x 2 = 4 quarter notes.
Only one thing. A dotted half-note. The dot extends the length of a note by one-half. There is nothing in notation that stands for a three/quarter note.
