Just the same as any other language, you need to learn the vocabulary (words) and the grammar (how the words are put together and how they change in different situations). Lakota (or the closely related Dakota) does not work anything like English, so you need to forget everything you ever learned about the English language.
You also need to know something about the religion and culture of the Sioux people; it is common to find terms such as yuwipi, meaning "tied one". Without understanding the background (a healer who uses the power of rawhide and stones to perform supernatural healing) this word would make no sense.
The Sungmanitu-Isna (Lone Wolf) website via the link below is a good starting point (look first at the phonological key), but you will quickly realise that the language is highly complex and far from easy to learn. It also helps if you have learned another foreign language so you can identify parts of speech and grammatical terms. There are also very different opinions even among Lakota speakers about the correct way to write Lakota sounds.
Engllish is the official and accepted language.
Both speak English now as well as their native tongues.

Yes the aborginals of the Sioux nation did and most still do. Sioux is a French word given to encompass the Lakota, Nakota, and Dakota tribes. I believe the languages for each tribe are slightly different, but the average age of a 'Sioux' speaking person is 64 or 65. Less and less young ones are learning the language.
Lakota people spoke Lakȟótiyapi, also referred to as the Lakota Language, Lakhota, Teton or Teton Sioux. It is a Siouan language still spoken by the Lakota people of the Sioux tribes.The Lakota language has approximately 2,000 speakers living mostly in northern plains states of North Dakota and South Dakota.Virtually all Lakota speak English as their primary language today.
