Aeris:
Don Corneo - The Wall Market's local pervert, Don Corneo has great taste to pick the "little slender" Aeris as his bride for the evening. He's even considerate enough as her loving husband to take her through it slowly, step by step. Their unholy matrimony is cut short after Cloud and Tifa bust in and Aeris threatens him to rip "them" off.
Kotch - In what could be described as one of Aeris's funnier moments, if Tifa is chosen by the Don, Aeris is sent down into the torture chamber to entertain Corneo's henchman, Kotch. While there, she is comically chased around a table by him. He's not exactly looking for a committed relationship, but gets more than what he bargained for when she kicks him in the crotch making him tumble down the stairs. And like the kind person that she is, Aeris says she's sorry.
Tseng - He's the only one Aeris has known since childhood, and the only one determined return her to captivity as well. He may have been the one to slap Aeris back into the helicopter and he might be the one responsible for kidnapping her and taking her back to Shinra headquarters, but it's not that he doesn't care. He does indeed tell Aeris to take care and stay out of Shinra's way when it's uncertain when they will meet again. In the Temple of the Ancients as he lies dying, he even blames the start of his bad luck after letting her go. Aeris doesn't cry, but is still mourns his departure.
Red XIII - Hojo's answer to lending a helping hand to endangered species, Red is placed with Aeris in a laboratory tube with the high hopes of mating. Alas, bestiality even in the FFVII world is frowned upon. In Red's defense, it's not as though he likes two-legged things anyway. However, towards the end before facing Sephiroth, he admits he actually liked the attention Aeris gave him and that he wanted to apologize for when they first met.
Cait Sith - He might be a toy cat on a robotic mog controlled by Reeve, the head of Shinra's Urban Development, but he's not without his charms nor would he mind having Tifa as his nurse. After Aeris asks Cait to predict her compatibility to Cloud, he tells her that it'll cost exactly one date. Also, before he leaves to solve the Ancients' puzzle, he is so happy when she tells him to be strong.
