You can use them. 
They’re used to make items in your Forge.
Each Forge level lets you make a different item, and requires different ingredients.

So you can’t pick the ones you want to use??? It’s using the same 2 things or is something else I need to do to use them??
Each item has a particular recipe to make it. But by the time you have your Forge maxed to level 20, there will be a use for every ingredient.
Here’s a full list of all of the possible items and their ingredients:

Worry not, there will come times when you’ll literally feel a powerful urge to throw your phone away because the tiles won’t match or your heroes won’t charge in time, but you’re gonna love every second of it!!! 
It’s an addictive ride…
Being free to play (F2P) as in spending no money on the game will slow you down quite a bit, but perseverance and time can bring you the almost the same things as money
Why does no one read the wiki? Oh, that’s right, no one tells them to.
New players, there is an E&P wiki. Read it
Trying to post about a bug, where my aife is level 20 but is a black hole and will not let me start using skill tokens.
@echbearsfan Welcome to the Forum!
As @JonahTheBard said, Aife’s special skill needs to be maxed to unlock the Talent Grid.
Now that she’s at maximum Level, you can increase her special skill with 100% chance by training her with another Aife. If you need to increase her special skill multiple times to get to 8/8, train her with a single Aife one at a time for each special skill level you need.
Some further information from a similar question above (this person was asking about 1* Sharan):
Since Aife is a 1* hero, and relatively common to get from World Map stages or training camp level 1/2, feeding a duplicate Aife is your best bet.
