Potentially all

Doing some quick math you think you could afford one or two of them if you want to fully mod them with all the options you could want such as animal features, physical augmentation, mental manipulations like complete love and devotion, and memory alterations to make them act more to your tastes. Resetting them to when they were freshly caught would also put a massive dent, you think grimly. As your gaze go over Erza and Diana, you are reminded of the fees and regulations associated with purchasing and modifying the more valuable characters.

You figure you could purchase four or five of them if you want to add only basic mods, like minor mental manipulations like basic loyalty and acceptance. Or light touch ups to their physical appearance like manipulating hair length, quality tattoos or slight changes to their body. Knowing your neighbors and, as you look over Laura and Erza, the characters' personalities you think some security features like control and locator chips would be in order.

You know you could potentially get all of them if you decide to take all of them home as they are now. You think over the general prices for named characters and you think that you might have enough if you only get GPS and minor changes for a couple of them. Once you buy them and get them home, you will have plenty of time to get after market mods and at home mod kits later though. You figure that a little bit of patience might be in order.

This all depends on the estimate the checkout desk gives you, just Diana and the Erza will likely take over half of your funds. You look over the former pony girls to decide which ones you might want and why.
