The numbers say, no. To get the 4-element (Riff) and the four 3-elements (Scups, Pompom, T-Rox, and Congle), you would need 16 beds: (1 * 4) + (4 * 3) = 16. Therefore, you can't get them all active on your island unless you upgrade to at least the Comfortable Castle.

But, as you indicated:


 * The Comfortable Castle upgrade costs 1.5M coins
 * You have 7M coins available
 * You aren't planning on spending the coins on the Water Island

So where's the problem? You can easily get the Castle upgraded, and it's not going to interfere with any other plans that you've mentioned. In fact, with the 7M coins you mentioned, you could easily do both, upgrade the Castle and buy the Water Island.

The alternative, if for some reason you don't want to upgrade your Castle, would be to buy a Hotel Structure, and swap your monsters in and out of it for breeding. Some of them wouldn't be active and visible then, though. You'll probably need a Hotel in any case, since the 1- and 2-element monsters you already have require 10 beds. Added to the 16 beds for the 3- and 4-element monsters, that's a total of 26 beds required.

Therefore, you're going to need either the Spacious Castle, or the Comfortable Castle and the Humble Hotel. Either way, that gets you up to 28 beds, and either way is still well within your budget.
