Question: I'm new to guitar. I don’t really understand the tuning and its relationship with music notes. Can someone explain how I can get my guitar tuning to

F, Bb, D, F, Bb, F (Capo on 1).

Answer: 
I am going on the assumption that your notes are in order of low to high pitch. Standard tuning on guitar low to high is E,A,D,G,B,E. With the capo off the tuning you want is E,A,C#,E,A,E. This means from standard tuning the 2 lowest strings and the high string need no change. The D string must be tuned down a semitone to C#, the G string must be tuned down 3 semitones to E and the B string must be tuned down 2 semitones to A. Once you have done that putting the capo on the first fret will give you the notes you want, F,Bb,D,F,Bb,F.
This is less me answering your question than figuring out your context.

Remove the capo and we get

That's likely high-to-low. Guitarists tend to talk tunings low-to-high, but this is fine. Then we get that C# on the G string, and that's awful sharp. You'd need a far smaller third string, and no.

So it *is* low-to-high. Down a half step on the fourth string. I would probably try to tune up to E but the this works. Then, on the third string, we're down a minor third instead of up a second. Then with the second string, we're down a major second instead of up, getting the A instead of the C#. The major chord across the second, third and fourth strings is kinda the core to guitar fingering, but if that's the tuning you need, the open Bb the song needs, there you go.

So, low-to-high, that would be standard, standard, down a half step, down three half steps, down two half steps, standard. Capo and recheck and there you go.

It would be more "normal" to get there by tuning to an open G like

then capoing on the third fret.

This would seem more natural to most guitarists. But I don't know the song and arrangement and fingering you're trying to get to. I could see that being some fingerstyle player's fave tuning, but I don't get it.

Best of luck.
