Need somone's help for identification

[abhijit]

Some Aerides species of my collection(Like Aerides odoretum, Aerides multiflorum) were bloom last year. A new species is flowering now and I am not sure, is it Aerides fieldingii?
One another question is, two vanda species were open there petals three days ago and I saw their colours are rather deferent. Both are same fragrant. One of them is my local variety and I know that’s roxburghii Rasna. But I don’t know another’s name. Are they same species or different? I saw somewhere someone described the last one as “Checkered Vanda”. Is it correct? Is Vanda tessellata the synonym of Vanda roxburghii? I need someone’s help.

The last two pictures are both Vanda tessellata.

I think the first two pictures are Aerides fieldingii (Aerides rosea).
