Since they have already been moved and are in more permanent 'home' it is probably best to remove those plastic cups for all the reasons already mentioned.
Plastic cups being used as humidity domes are for attempting to produce a clone where the cutting does not have a root system yet and might not be able to draw up enough water.
Just a note to keep in mind but put those saucers away until needed. Get some smaller ones that match the size of the pot. Judging by what I can see those types of saucers are not rigid enough to hold up if you try to pick the pot and saucer up at the same time. Not a major point but it might make doing maintenance chores easier later on when the plant is bigger.
