They all sound so similar to me, I want to know how I can tell the difference these since they make the same sound. (Please excuse me if I’m wrong I’m very new to Japanese and currently learning hiragana)
I'm Mikiko Iwasaki. すみません。My name probably appears in Kanji. I am a native Japanese speaker and a professional Japanese language teacher. Historically, 「じ」and 「ぢ」have different sounds, and「ず」and 「づ」have different sounds. But in modern Japanese, they are pronounced the same in most areas in Japan, じ[ji], ぢ[ji], and ず[zu], づ[zu]. As Ellettさん writes, ざ[za] and だ[da] have different sounds. ざline syllables have [z] + [a], [e], [o], and だline syllables have [d] + [a], [e], [o]. If you can pronounce or if you can check the pronunciation of "Zambia," the name of the country, and "diamond," the first sounds of each word are similar to ざ[za] and だ[da]. So, please try.
