ظَلَمْتَ — you (one man) did wrong; the attached subject pronoun corresponds to أَنْتَ.
صَبَرْتُمَا — you two were patient; it corresponds to أَنْتُمَا.
شَكَرْنَا — we gave thanks; it corresponds to نَحْنُ.
جَلَسُوا — they (men) sat; واو الجماعة is the attached subject pronoun.
These 4 answers use a pronominal doer, so no separate explicit noun subject is needed.
