No. Grandpa refers to the male parent of your parent and grandma refers to the female parent
I don't believe the order is relevant; however, I personally say "Grandma and Grandpa."
Grandma- Grandmére Grandpa-Grandpére
In French, children say "grandpa" as "papi" and "grandma" as "mamie".
Grandma is "бабуся" (babusya) and grandpa is "дідусь" (didus).
In Haitian Creole, grandma is "granmoun" and grandpa is "granpè."
Grandma in German is "Oma" and grandpa is "Opa".
Given that grandma and grandpa are probably conceived as a unit, or partnership, rather than separately, I would favor the latter construction, grandma and grandpa's house. However, the other form would also be acceptable.
A grandma is either your mother's mother or your father's mother.
