Don't know much about hoyas, but IIRC - Krimson Queen leaves is green with white outer margins, center of Krimson Princess is creamy with green borderlines.; so #5; imay be Krimson Princess

#3: maybe H. australis?

Thanks, Rina. I’ll add that label. i just found a label that says ”Sunrise” ... That would be the reddish one (#4). Two down and four to go.

#2 looks like Lacunosa

#3 looks like cumingiana

#4 looks like sunrise

#5 looks like krimson princess

Thank you, Tika Land. That's brilliant. I'll add 'ta' to the end of #6. now we're just missing #1.

Just found the tag for #1 ... It’s MPR02.
