Congrats on your first blooming vanda.
Vanda are warm growing orchids. But the blue vanda can be grown in temperate region as well.
Once temperature part is settled, you have to look into light. Is your first vanda strap(broad) leaves type? Then care will be similar for your newly bought orchids since they are strap leaves type too. If your first orchid is terete or semi-terete type, then give new orchids lesser light then the first one. Same care can be given except for light adjustment.
