Against which sicilian variations can I play English attack?

@1
"It was always tough for me to face the Sicilian." ++ The Sicilian is played by stronger players.
"I was afraid to play the open sicilian as there are many variations to learn." ++ True.
"I played closed sicilian all these days." ++ Good.
"after crossing 1500 it has become a nightmare playing closed sicilian."
++ That is nonsense. Spassky, Smyslov played it at world championship level.
You do not lose because of the opening, you lose because you make tactical mistakes.
Do not blame the opening. Analyse your lost games.
"if I can play English attack against all variations."
++ Yes, but if you think you will lose less because of it, then you are mistaken.
#4 not really, after 6. f3 e5 7. Nb3 Be6 8. Be3 d5 Black is going to trade everything in the center and you can forget any attack. The best is 8. Nd5 but White should castle short and its not really an english attack

That is still part of the English Attack complex.
Against the classical, you can play the Richter-Rauzer and then f3 instead of f4 to get an English attack setup. I think this approach is more testing than going for 6. Be3 or f3. The disadvantage is that black has several deviations from 6. ... e6 that are not often played [I only play them in blitz], not so strong but you'd need to prepare for. -my opinion only-Bill
