In this hypothetical, assuming you COULD add multiple fairies.
They would be all rolled at the same time, but not stack up to 100%.

If you may have noticed in farm events, if you combine multiples of your event unit, you might get +2 or +3 skill ups. If you could use all four slots for four rainbow fairies, I assume each of them would be rolled individually.

Say you have a Momiji at 9/10 skill and you use all four slots, and the first fairy gives you +1SU, then you wasted 3 fairies. The lock on 1 Fairy per roll is likely to help people save fairies and avoid spending too many at a time.

The effects do not stack from what I noticed, so really, throwing four in the bin would not only potentially waste your fairies, but also do nothing aside from save time. (With the exception maybe if you are currently at 1/5 or 5/10 skill levels)
