Working from right to left (anti clockwise) there's Hedera helix (the one with the trailing stems and small leaves), then what appears to be a Parlour Palm, then Spathiphyllum (Peace Lily) and lastly, the one with the feathery, white variegation down the centre of the large leaves. That one is the one I'm not entirely sure of - it's either a Dieffenbachia or one of the Marantas, but I can't find one with exactly that variegation in either category. Luckily, though, the light situation and care is similar for both - bright daylight is best, no sun, but Maranta prefers a somewhat higher humidity than Dieffenbachia, so grouping it together with one or two of the other plants should help with that, and it won't do any harm to do it if its Dieffenbachia either.
The Hedera (ivy) will tolerate some sunlight, it will help to keep the variegation, but not in the middle of the day through a window, especially in summer. Otherwise, it does well in shadier conditions - prefers a cooler spot, it does not like temperatures over 70 deg. F. Both the Parlour Palm and the Spathiphyllum prefer average to reasonably bright light conditions, but no sunlight. None of these plants will appreciate being near a heat source, like a radiator or electrical equipment that gives off heat.
Watering is the same for all - during spring and summer, water when the surface of the potting soil feels dry to the touch, but not shrunken from the sides of the pot, water well, allow to drain down freely, then empty out any outer tray or pot after 30 minutes so the plants are not left sitting in water. Check the plants every 5-7 days to see how dry they are - lifting the pot to check the weight is another way to confirm whether water is needed or not - it will feel much lighter when it's dry. In winter, all these plants will need a little less water, or watering less often, depending on the warmth of your home.
I don't know where you are or whether you can get Baby Bio liquid houseplant food, but 5 drops of that in a pint of water given about every fortnight during spring and early summer will be plenty. Easy to do when you water.
You might be interested to know that these four plants (assuming the one I'm not sure of is Dieffenbachia) are good at taking household pollutants like formaldehyde out of the air and, provided they're not kept far too wet, have the capacity to suppress or reduce air borne mould spores and bacteria. Pets and children should not be allowed to chew or eat any of them though.
The only other thing to say is that the Spathiphyllum appears to have a soil level almost to the top of the pot - I'm guessing its been topped off prior to despatch, but that makes it quite difficult to water, because there should be a gap at the top between soil and pot rim. You may find you need to repot it into a larger or deeper pot because its impossible to water it properly. You will likely find the Spathiphyllum needs watering more often than the others do, even in a larger pot.
