Made and Maid

Do you pronounce these two words the same way?

What about,

plane and plain
mane and main
male and mail

?

Yes to all of the above.

I pronounce them the same way. Are there any people that pronounce them differently?

Each pair are the same for me. But "there are those who consistently distinguish such pairs as 'mane' vs. 'main' (Swansea Valley) ..." according to J. C. Wells.
