The accessibility of the regions is very confusing at the moment because of the lack of official information, so I decided to ask the staff

 

1) What are the exact conditions of getting to Sevii Islands? Beating all Kanto gyms or beating the E4 too?

2) How to get to Jotho? Have to beat the E4 and Red or E4 is enough?

3) How to get to the Orange Archipelago?

4) What are the conditions to get to Love Island? Have to own 120 different Kanto Pokemon in my boxes, or is it enough to have them owned at one point? And how do evolutions count? A Charizard counts as 3 Pokes or only 1?

 

Thanks in advance :)

Orange Archipelago is not implemented yet for players.

1) What are the exact conditions of getting to Sevii Islands? Beating all Kanto gyms or beating the E4 too?

You have to be Kanto champion in order to access the Sevii Islands, which means you have to defeat the Elite 4; and have membership too.

2) How to get to Jotho? Have to beat the E4 and Red or E4 is enough?

You can't reach Johto without defeating the Elite 4.

3) How to get to the Orange Archipelago?

Orange Archipelago is being worked on and it's not available for players right now.

4) What are the conditions to get to Love Island? Have to own 120 different Kanto Pokemon in my boxes, or is it enough to have them owned at one point? And how do evolutions count? A Charizard counts as 3 Pokes or only 1?

You have to catch 120 different Kanto Pokemon, each species is different from other. Charizard counts as 1, although if you got it from a charmander then it counts as 3.
