Dragana is a bit confused. Haber (hay) means there "is/are", and Estar means "Be" in the sense of location. Estoy en mi casa --> I'm in my house Mi hermana no está aquí --> My sister is not here. Hay cuatro vasos en la mesa --> There are four glasses on the table Hay agua? --> Is there water? As Azimux told you, in spanish the word order is much less strict than in English. If you change the order, you also change the emphasis you give to the words, but it is more or less the same. ESTÁN todos en la playa? Is everybody at the beach? Here the emphasis goes to the verb. TODOS están en la playa? Here, you give emphasis to "everybody"

Hay=have... Estan=there are! Example: Todos estan a la playa,y estan todos a la playa,es igual..te van a entender :)
