First, all of these can be enjoyed in the house while they are blooming. Details of care can be refined if you can tell us where you live.
1-2 Cymbidium. Needs bright light to bloom, and a significant (20-25 deg) temperature difference between day and night in the fall to bloom. If you don't have go below freezing, it needs to grow outside. If you live where it gets cold, you can keep it in for the winter (giving as much light as possible) , put outside as soon as danger of frost is past.
3-4 is Oncidium ("dancing lady"). Good light but not as bright as Cymbidium. Can take down to about 40 deg F at night, needs to be in the house if colder than that outside.
5 is Paphiopedilum. It wants to be more shady, can tolerate cold down to about 40 deg. F, colder needs to be inside. (This "bulldog" type Paph is very adaptable and can be easily grown indoors since it does not need a lot of light. It also doesn't like a lot of summer heat so if you are in hot area, house is better.
6 is Miltoniopsis ("pansy orchid") These don't like extremes of either heat or cold. They also should be on the shady side if outside, but in most places needs to be inside for the winter, possibly hot summer as well.
7 is nobile-type dendrobium. These need to be kept quite dry in winter, and on the cool side, needing a night time temperature drop as well as little water and no fertilizer to bloom - water and fertilizer can be increased in the spring when new growth appears. Can tolerate winter nights near freezing if you are in a frost-free area. Since it's in bloom, you can give it some water. Do the drying-out regimen next winter.
In all cases, when you water an orchid, water it well - let water run through the pot. Then let it dry out somewhat before watering again, never let them sit in water.

There is no rush to repot any of these - unless you see an obvious problem, wait until they're through blooming. Ideal time to pot most orchids is when they are producing new growth. So for most, waiting until closer to spring would probably be a good idea.
