Es bueno = is good. thank you = gracias. If somebody tells you, for example, es bueno verte de nuevo (is good to see you again) that is a compliment, so you can just said thank you very much (muchas gracias). the same if somebody as es bueno tu something you gave them or did, only say gracias or muchas gracias to be polite. Cheers!
esta = this (feminine). This is a demonstrative adjective. Esta camisa es nueva.. (This shirt is new) If you want a demonstrative pronoun, you use an accent over the e: Ã©sta. Ãsta es mi hermana.. (This is my sister) Now, there is another word with the same spelling, or almost the same, because it takes an accent over the a: estÃ¡. It's a form of the verb estar (to be, for the grammatical persons usted, Ã©l and ella in the present indicative) MarÃ­a no estÃ¡ en casa..
