Words for meals in English are:
breakfast: first meal of the day, eaten in the morning
lunch: a meal eaten around noon
supper: a meal eaten in the evening
dinner: the biggest meal of the day. For most Americans that's the same as supper, though some people have their big meal at lunch time and so call that dinner.
brunch: a meal too late to normally be called breakfast and too early to be lunch, and/or which takes the place of breakfast and lunch.
There is no commonly-used word for a late lunch or early dinner or supper. Dinner times vary pretty widely. A big meal eaten anywhere between about 5:00 pm and 10:00 pm would routinely be called supper or dinner and no one would consider that strange. People sometimes say "we had an early dinner" or "we eat supper late" to distinguish.
