[name_m]Hi[/name_m] there!
What do you think of the following names? Any feedback would be much appreciated.
[name_f]Autumn[/name_f] [name_f]Faith[/name_f]
[name_f]Autumn[/name_f] [name_f]Hazel[/name_f]
[name_f]Autumn[/name_f] [name_f]Grace[/name_f]
[name_m]Welcome[/name_m]!
I think [name_f]Grace[/name_f] goes best in this instance.
I agree that among the three middle names you mentioned, Grace pairs best with Autumn.
I wouldn’t pick any of them as with (the very pretty) Autumn (and I’m in a country that uses Autumn, not “fall”), they sound too wordy - like the grace of Autumn, having faith only in Autumn, and the hazel colours of autumn leaves etc. You may like it that the name is more descriptive, so it take if that’s what you’re aiming for. And I agree with PPs that Grace - or even Faith - flows well.
Other options:
Autumn Elise
Autumn Shea
Autumn Lucy
Autumn Harriet
Autumn Cleo
Autumn Claire
Autumn Chloe
Autumn Estelle
Autumn Jane
Autumn Phoebe
Autumn Beatrice
Autumn Caroline
Autumn Daphne
I agree with @EloiseT about the word names.

Firstly absolutely love [name_f]Autumn[/name_f] 
However I think with [name_f]Autumn[/name_f] these names are a little descriptive and do not work the best as @EloiseT stated. I would be inclined to go with [name_f]Faith[/name_f] just because she’s a favourite of mine however personally I find that all three do not work the best.

Other recommendation:
[name_f]Autumn[/name_f] [name_f]Aurelia[/name_f] (Aurelia means gold, golden autumn, if u doesn’t mind the repetition in initials this combo can be cute)
[name_f]Autumn[/name_f] [name_f]Brooke[/name_f]
[name_f]Autumn[/name_f] [name_f]Rose[/name_f]
I think my favourite is [name_f]Autumn[/name_f] Faith…I like the connotations and the flow. [name_f]Autumn[/name_f] is my favourite season and I just love the colours…“like the colours in autumn so bright just before they lose them all” - autumn is peak brightness, peak strength of colour…it’s also the season of harvest and fruits being in their maturity…so there’s something poetic to the meaning of [name_f]Autumn[/name_f] [name_f]Faith[/name_f] - having a vibrant, beautiful and mature faith.
I also like [name_f]Autumn[/name_f] [name_f]Grace[/name_f]
