The most common is Litmus. Litmus is extracted from various Lichens and is a good indicator of both acids and alkalis. Some naturally occurring substances indicate only acids or alkalis such as cochineal and curcumin.
The common litmus paper is impregnated with the dye extract of the Lichen to act as an acidity or alkalinity indicator.
All PH (acidity and alkilinity) measuring devices work based upon whether they accept or donate protons and as such are infact themselves acids or bases.
For greater accuracy other dyes (other than the reactive element) are added to the PH detector which can be chemically engineered to give visible changes in colour at every step on the PH scale.

What plants can be used to make pH indicator?
If you are asking how to extract a chemical pH indicator from some plant type, I don't know. If you want to know a plant that indicates the relative pH of the soil it grows in, Hydrangea. Its flower's coloration is exactly like litmus paper's reaction to acids and alkalis.
What are industrial alkalis?
They are alkalis, such as sodium carbonate, used by industries, such as glassmakers.

What alkalis are in soap?
Soap is a product of reaction of fatty acids (present in vegetable oils and fats) and strong alkalis (NaOH or KOH). No alkali should be present in the final product - soap. If it is, this means that more alkali was used than necessary for saponification and the excess was not separated in the additional steps.
