No. Plain flour does not contain yeast. Some flour mixes do.
There is no yeast at all in enriched flour. Enriched flour has a few specific nutrients added to replace some of the nutrients lost when the bran and germ are removed from whole wheat to produce white flour. Yeast must be added to enriched flour if it is used to make bread. See the Wikipedia article linked below for additional information.
all flours make the structure of the bread
Salt and fat are added at the end of some methods of mixing bread dough so that they will not interfere with the incorporation of yeast into the flours or reduce the rising power of the yeast. However, when modern forms of "active dry yeast" are used, the salt and yeast can be added together, directly to the flour, with fats stirred in immediately thereafter.

No. It is a yeast, that's all.
Soft flours are those with low protein (gluten) content, such as cake and pastry flour.

Finer ground flours bleach faster. Different grains produce different color flours initially, from a yellowish white or pinkish white to a bright white.
No, all-purpose flour does not contain yeast. Yeast is a separate ingredient that is added to flour to make dough rise when baking.
