Welcome to the TP!
I went through and ID'd all of them with a corresponding number according to this picture:
(I went mostly left to right but forgot poor shovels at some point and doubled back for her)
I wrote down the name associated with each number and after in parentheses did a vague price estimate just to give you an idea. Obviously their actual prices depend a lot on condition but these are assuming they're in pretty good shape which I think a lot of these could get into if you're willing to put the time in and clean them up.
1) Dancing Butterflies ($7)
2) Lickety Split ($5)
3) Parasol ($2)
4) Baby Toe Dancer ($5)
5) Napper ($8 )
6) Pink Sweet Talkin' Pony ($10 - could be more if she still talks)
7) Diamond Dreams ($50)
8 ) Cupcake ($5)

11) Tropical Breeze ($7)
12) Windy ($4)
13) Forget-Me-Not ($5)
14) Swinger ($5)
15) Twinkler (MO?) ($7 if she's store, $12 if she's mail-order - you can tell this by if she has a firework symbol on her cheek)
16) Tiffany ($7)
17) Jangles ($5)
18 ) Sandcastle ($25)
19) Sea Breeze ($7)
20) 4 Speed ($20)
The Hat next to him belongs to Tex, I know those hats have value but I don't know how much. Hopefully someone else can advise.
21) Wind Whistler ($8 )
22) Ribbon ($5)
23) Baby Bright Bouquet ($6)
24) Galaxy ($9)

33) Sea Star ($5)
34) Pina Colada ($7)
35) Daddy Bright Bouquet ($10)
36) Blossom (FF or CF?) ($7 for CF, $11 for FF - you can tell if she's flat footed by if her feet are flush instead of being concave like all the other ponies, based on the picture I'm guessing she's CF)
37) Peach Blossom ($3)
38 ) Beachcomber ($10)
39) Surf Rider ($6)
40) Sticky ($6)

56) Baby Moondancer ($6)
57) Mommy Bright Bouquet ($4)
58 ) Baby Brother Sweet Celebrations ($5)
59) Baby Waddles ($15 at least, especially with his bandana, might be worth taking offers on him)
60) Shovels ($22)
Now, with all this in mind I have some suggestions for ways to sell based on how much time you want to invest. Selling individually will always get you the best price but you have a decent bulk of lower priced ponies so it might be worth selling those as a lots.
Ponies you should definitely sell separately -
6 - the Pink Sweet Talkin pony, especially if she works
7 - Diamond Dreams, your most valuable pony
18 & 60 - Sandcastle & Shovels - these are actually twins that go together, depending on how they clean up you could get a good amount of money for them
20 - 4 speed
28 - Rattles or Tattles
29 - Baby Palm Tree (assuming that's her)
23, 35 & 57 - the Bright Bouquet family might be worth selling together, dad will fetch the most though
48 - Pearlized Baby Blossom
50 - Pearlized Baby Firefly
49 - Baby Waddles
You have two other sets of baby newborn twins as well, Jangles & Tangles and Sticky & Sniffles who might make sense to sell as a pair.
I know nothing about Fairy Tail birds, they aren't MLP but other people here collect them, hopefully someone else can advise.
