Elders? eg. listen to your elders -- is an in/famous retort or order. Though theres none i can recall for direct referencing eg call your (older) sister/brother. And
elder as a whole, encompasses both peers ie same/close generation and or age group eg siblings,cousins and those further away eg grandparents, parents, parent's siblings,..
senior vs juniors which can be used somewhat directly. And maybe
superiors but both imply an individual rank/relation outside of merely being younger. Not to mention evolved or original meanings ie senior vs young/youth and superior vs inferior.
sir/mr/mam/miss is occasionally used in polite/respectful context. Though casually or everyday with peers eg classmates or seniors, would be odd.
All are also very much more known as titles now, than noun or address.
It would be truly impossible to find a real (everyday) equivalent for sure, as age-awareness is inbuilt into their everyday speech incl sentence structures. whilst in english, it'll be a rare or very telling upbringing to have either younger OR older to address their elder siblings/peers even, as sister/brother.
