Only one of each.

Each implants take up a specific slot, and each slot is meant for implants that affect a specific attribute. For instance, Perception implants always go into slot 1; Charisma implants always go into slot 5 etc. Since you can only have one implant per slot, you also only get one implant per attribute.

Now, before you go and slot in every last implant at max bonus in those five slots, it's worth pointing out the existence of jump clones, which you get access to by training the science skill Infomorph Psychology. With this skill, and with the right standing (either 8.0 with a suitable NPC corp or through connections with the right player corps), you can create copies of yourself that are really intended to let you travel across the galaxy in a single click, but which also let you store implants in a way. Each jump clone has its own unique set of implants and they're often used to “store” expensive learning clones when people plan on getting blown up a lot: just jump into a clone that has no implants, and nothing get lost (except the clone upgrade cost) if you get podded. The downside is, of course, that you don't have the benefit of those implants.

The same tactic can also be used to create a middle-of-the-road strategy to at least lower the cost of pod death. Instead of having all implants in one clone, you have different clones implanted with different combinations and only with the implants that actually affect your training. So instead of filling up a single clone with all five hideously expensive +5 implants, you take a jump clone and only implant it with two +4s — the difference in training time is minimal and the loss is massively reduced, not just because you go from +5s to +4s, but also because you only lose two of them rather than a full set of five.

Thanks for the help, all clear now!
