Total index=25  
Logs/day=50gbx2(copies)=100gb  
Shards/day=25x2=50 shards  
Log retention 60 days  
Logs for 60 days=100x60=6Tb  
Shards for 60 days=50x60=3000

So we are planning to use 3 master node with 8gb heap 6 hot data node each with 1tb ssd and 64gb ram and 2 client node with 8gb heap size  
In hot node we keep data of 60 days.  
My question is if we want this data (60 days data) in warm node does it also need 6tb storage and same heap size for retaining 60 days data.

Why 50 shards for 100gb data? That sounds excessive.

We have 25 index and the 25 index size is 50gb including replica 100gb

That is a quite small average shard size. I would recommend you try getting to an average shard size above 10GB.
