Post clear photos showing any details like leaf attachment, undersides, flowers, fruits/seeds, etc. on the Name That Plant forum. It is very rare that one of the experts there will not accurately ID the plant!! And be sure to divulge where in the world the plant is growing. Limit the number of different plants in each post to just one or two as it starts getting confusing with too many.

Once you have the plant identified, you can find various online resources that will tell you growing conditions and care requirements.

As far as I can tell none of the plant pics you posted is a jasmine. The third plant with white flowers looks like Nerium Oleander. I have mainly encounter pink flowered variety.

Generally speaking, tropical plants need a lot of light and warmth. Indoors it is hard to provide the required amount and levels of light unless you have a sun room or very large windows facing the Sun. Plants that have adapted to grow in shade are much easier house plants.

Most house plants suffer because the soil stays too wet too long with very little air in the soil. Most commercial bagged soil are poor choice for container growing - they hold too much water and have very little air.

Soil needs to be free draining loose textured soil. If you would like to spend some time understanding soil start here: https://www.houzz.com/discussions/container-soils-water-movement-and-retention-xxii-dsvw-vd~2842847
