Q.Is it ok to plant impatiens in same area as ones before that died back in August from some airborne fungus disease? It’s been
at least three years since they were planted there. What other flowers would be a good substitute for impatiens if I can’t replant them there. Impatiens are so showy and have such an abundance of flowers all summer. I really miss them.

It's best not to because of replant disease if you are sure your plant died of a fungus and not a cultural problem. The article below explains more.
You could plant your impatiens in pots and set them on the same place or remove the questionable soil and replace with fresh soil and plenty of compost.
Other plants that could go there would need to be shade tolerant (I'm guessing this is a shady place.)
