How to find the list of host institution for Marie-Curie individual fellowship?
There's no list, any legal entity in the EU or in a partner country is eligible: http://ec.europa.eu/research/participants/data/ref/h2020/wp/2018-2020/main/h2020-wp1820-msca_en.pdf p.76
As far as I know it's more common to apply with a university or a research institution, but companies can be host institutions as well.
Does it mean that the host institution must have already received or get approved for Marie-Curie individual fellowship?
No, but it's possible that the institution would have to be registered on the EU portal (this is how it works for H2020 proposals, I'm not sure about Marie Curie actions).
The eligibiity conditions are rather easy to satisfy, but in order to have any chance of success it's very important to understand that the selection relies very strongly on the excellence of the research proposal in collaboration with the host institution. This means that before applying, any serious candidate must contact a potential PI and design a detailed research plan with them. I think it's crucial to understand what the EU expects to achieve through these grants in order to write a decent application, because they are not just giving away funding to kind junior researchers :)
Some EU institutions have a specialized office to help applicants write good applications. If the target host institution does it's a really good idea to contact them and ask them for advice, it can drastically increases your chances.
(and yes, the EU website is a monster, but given time one can find really useful information in there)
