Yes, you should be able to use CSS tweaks to customize those elements. Below is an example to showing how.

You can add the following CSS tweaks in the Appearance -> Customize -> Additional CSS interface of your admin dashboard to make the font size bigger and change the color to blue:

.asp-multicurr-select-container label {
    font-size: 20px;
    color: blue;
}
.asp-multicurr-select{
    font-size: 20px;
    color: blue;
}
.asp-multicurr-submit-btn {
    font-size: 20px;
    color: blue;
}

This is just an example. You can experiment with the different CSS values to see what you like.
