Agree with Michel Bariche. Look at this https://ejournals.epublishing.ekt.gr/index.php/hcmr-med-mar-sc/article/download/12006/12015 

 Dear, 

         Please take jellyfish image within the water .Otherwise identification is difficult process. 

First image is Crambionella stuhlmanni. It is common species in the  East coast of India.

Second image without oral arm I think this specimen has violet Steak in the exumbrella. So it is Thysanostoma loriferum .

Third image is  juvenile stage of Cyanea sp.

Fourth image may be Netrostoma sp. If you have this specimen  please take photos within aquarium tank and send me. I will try to identify .

Fifth one is Pelagia noctiluca .

Please give numbers to the images for identification .

I hope this helps, but if you need more assistance, please let me know! My email is [email protected]

Sincerely, 

Riyas A

I totally agree with Riyas Abdul on the identifications, they are not Cassiopea 

The fourth might be Cephea vs Netrostoma because I can see the smaller spikes in between the larger spikes on the bell, typical for Cephea.
