You will need to separate out that green part or it will take over and crowd out the proper 'Loyalist' because it will grow much faster.
As far as placement, you are the final judge. But bear in mind the ultimate size of the hosta and the shape of the mound. For instance, you probably don't want a host with an upright habit (vase shaped) right at the edge of the garden. And you don't want minis in a place where they will get lost under larger hostas.
Think of the colours in the leaves and plant colours that compliment each other. I like these together because the largest one, 'Sara' gets more yellow during the season, the one in front, 'Janet' gets white during the season and the one in back, 'So Sweet' has yellow margins.
I like 'June' and 'Bulletproof' together as the blue in 'Bulletproof' has a yellow cast at times and both colours compliment 'June'.
'Loyalist' is a sport of 'Patriot' and the colours are reversed. Others in the family would look good with these too.
'Aristocrat' and 'Remember Me' are roughly reversed colours and look nice together.
Include some solid colour hostas to give the eye a rest. And finally, remember that nobody gets it right all the time. And plants don't always grow at the rate you expect them to. Study the effect during the season and in late summer or early autumn, move them around to places where they work. (Do take pictures after you move them and title those pictures; so that the following spring you will know where to look for them). Don't forget to enjoy them!
