Welcome to the Orchid Board! Both of those are very beautiful flowers. I wouldn't be able to choose just one Phalaenopsis.
You are right - you need to know the type of orchid to find out how to care for it. Yours appear to by hybrid Phalaenopsis. Care for most of the hybrids with round, white-to-pink-to-yellow and spotted flowers is the same.
They prefer bright shade with no direct sun, but you might need extra light in a Finnish winter.
They prefer not to have temperatures much below 15-20C, and even that is low for them. They are happier from 25-35C but will grow at lower temperatures.
They prefer to be watered well, then allowed to go dry. But they shouldn't stay dry too long.
Regular, very small amounts of fertilizer help them grow and bloom better. However, fertilizer is the least important thing for them.
Here is a good thread on Orchid Board dealing with Phalaenopsis:
The Phal abuse ends here.
There is another group of Phalaenopsis with more star-shaped flowers. They generally have fewer flowers at a time, with flowers much shinier and waxier than the big round ones, often with substantial fragrance, on flower stems that continue producing flowers over many months to years. The leaves are much paler green and more shiny. They are not commonly sold in markets so you are not as likely to see them. This group of Phalaenopsis species and hybrids should stay warmer than 18C and does better with higher humidity.
By the way, what is the shrub with red flowers outside the window?
